This tokenizer is not used in any RWKV models yet. I plan to use it for the future multilang RWKV models.

Benefits:

* Good support of most languages, from European to CJK to Arabic and Hindi and more.

* Clean vocab. Good for code too. Vocab size = 65536 (use 0 for <|endoftext|>).

* Good at numbers: the numerical tokens are '0'~'9', '10'~'99', ' 0'~' 9', ' 10'~' 99'.

* Very easy tokenization:

** The input text must be in UTF-8.

** Greedy encoding: always pick the longest (in bytes) token (with the highest id) that matches your UTF-8 bytes.

* The tokenization result is surprisingly good, because the vocab respects word boundaries and UTF-8 boundaries.

For 10x faster speed:

打ち上げは米テキサス州の東海岸で行われた。無人の試験で、負傷者はいなかった。
打ち上げから2～3分後、史上最大のロケットが制御不能になり、まもなく搭載された装置で破壊された。
マスク氏は、数カ月後に再挑戦すると表明した。
スペースXのエンジニアたちは、それでもこの日のミッションは成功だったとしている。「早期に頻繁に試験する」ことを好む人たちなので、破壊を恐れていない。次のフライトに向け、大量のデータを収集したはずだ。2機目のスターシップは、ほぼ飛行準備が整っている。
マスク氏は、「SpaceXチームの皆さん、スターシップのエキサイティングな試験打ち上げ、おめでとう！　数カ月後に行われる次の試験打ち上げに向けて、多くを学んだ」とツイートした。
アメリカでのロケット打ち上げを認可する米連邦航空局（NASA）は、事故調査を監督するとした。広報担当者は、飛行中に機体が失われた場合の通常の対応だと述べた。
マスク氏は打ち上げ前、期待値を下げようとしていた。発射台の設備を破壊せずに機体を打ち上げるだけでも「成功」だとしていた。
その願いはかなった。スターシップは打ち上げ施設からどんどん上昇し、メキシコ湾の上空へと向かっていった。しかし1分もしないうち、すべてが計画通りに進んでいるのではないことが明らかになった。'''

UTF-8 decoder capability and stress test
----------------------------------------

Markus Kuhn <http://www.cl.cam.ac.uk/~mgk25/> - 2015-08-28 - CC BY 4.0

This test file can help you examine, how your UTF-8 decoder handles
various types of correct, malformed, or otherwise interesting UTF-8
sequences. This file is not meant to be a conformance test. It does
not prescribe any particular outcome. Therefore, there is no way to
"pass" or "fail" this test file, even though the text does suggest a
preferable decoder behaviour at some places. Its aim is, instead, to
help you think about, and test, the behaviour of your UTF-8 decoder on a
systematic collection of unusual inputs. Experience so far suggests
that most first-time authors of UTF-8 decoders find at least one
serious problem in their decoder using this file.

The test lines below cover boundary conditions, malformed UTF-8
sequences, as well as correctly encoded UTF-8 sequences of Unicode code
points that should never occur in a correct UTF-8 file.

According to ISO 10646-1:2000, sections D.7 and 2.3c, a device
receiving UTF-8 shall interpret a "malformed sequence in the same way
that it interprets a character that is outside the adopted subset" and
"characters that are not within the adopted subset shall be indicated
to the user" by a receiving device. One commonly used approach in
UTF-8 decoders is to replace any malformed UTF-8 sequence by a
replacement character (U+FFFD), which looks a bit like an inverted
question mark, or a similar symbol. It might be a good idea to
visually distinguish a malformed UTF-8 sequence from a correctly
encoded Unicode character that is just not available in the current
font but otherwise fully legal, even though ISO 10646-1 doesn't
mandate this. In any case, just ignoring malformed sequences or
unavailable characters does not conform to ISO 10646, will make
debugging more difficult, and can lead to user confusion.

Please check, whether a malformed UTF-8 sequence is (1) represented at
all, (2) represented by exactly one single replacement character (or
equivalent signal), and (3) the following quotation mark after an
illegal UTF-8 sequence is correctly displayed, i.e. proper
resynchronization takes place immediately after any malformed
sequence. This file says "THE END" in the last line, so if you don't
see that, your decoder crashed somehow before, which should always be
cause for concern.

All lines in this file are exactly 79 characters long (plus the line
feed). In addition, all lines end with "|", except for the two test
lines 2.1.1 and 2.2.1, which contain non-printable ASCII controls
U+0000 and U+007F. If you display this file with a fixed-width font,
these "|" characters should all line up in column 79 (right margin).
This allows you to test quickly, whether your UTF-8 decoder finds the
correct number of characters in every line, that is whether each
malformed sequences is replaced by a single replacement character.

Note that, as an alternative to the notion of malformed sequence used
here, it is also a perfectly acceptable (and in some situations even
preferable) solution to represent each individual byte of a malformed
sequence with a replacement character. If you follow this strategy in
your decoder, then please ignore the "|" column.

The following sequences are not malformed according to the letter of          |
the Unicode 2.0 standard. However, they are longer then necessary and         |
a correct UTF-8 encoder is not allowed to produce them. A "safe UTF-8         |
decoder" should reject them just like malformed sequences for two             |
reasons: (1) It helps to debug applications if overlong sequences are         |
not treated as valid representations of characters, because this helps        |
to spot problems more quickly. (2) Overlong sequences provide                 |
alternative representations of characters, that could maliciously be          |
used to bypass filters that check only for ASCII characters. For              |
instance, a 2-byte encoded line feed (LF) would not be caught by a            |
line counter that counts only 0x0a bytes, but it would still be               |
processed as a line feed by an unsafe UTF-8 decoder later in the              |
pipeline. From a security point of view, ASCII compatibility of UTF-8         |
sequences means also, that ASCII characters are *only* allowed to be          |
represented by ASCII bytes in the range 0x00-0x7f. To ensure this             |
aspect of ASCII compatibility, use only "safe UTF-8 decoders" that            |
reject overlong UTF-8 sequences for which a shorter encoding exists.          |
                                                                              |

With a safe UTF-8 decoder, all of the following five overlong                 |
representations of the ASCII character slash ("/") should be rejected         |
like a malformed UTF-8 sequence, for instance by substituting it with         |
a replacement character. If you see a slash below, you do not have a          |
safe UTF-8 decoder!                                                           |

5.3 Noncharacter code positions                                               |
                                                                              |
The following "noncharacters" are "reserved for internal use" by              |
applications, and according to older versions of the Unicode Standard         |
"should never be interchanged". Unicode Corrigendum #9 dropped the            |
latter restriction. Nevertheless, their presence in incoming UTF-8 data       |
can remain a potential security risk, depending on what use is made of        |
these codes subsequently. Examples of such internal use:                      |
                                                                              |
 - Some file APIs with 16-bit characters may use the integer value -1         |
   = U+FFFF to signal an end-of-file (EOF) or error condition.                |
                                                                              |
 - In some UTF-16 receivers, code point U+FFFE might trigger a                |
   byte-swap operation (to convert between UTF-16LE and UTF-16BE).            |
                                                                              |
With such internal use of noncharacters, it may be desirable and safer        |
to block those code points in UTF-8 decoders, as they should never            |
occur legitimately in incoming UTF-8 data, and could trigger unsafe           |
behaviour in subsequent processing.                                           |
                                                                              |
Particularly problematic noncharacters in 16-bit applications:                |
                                                                              |

  Σὲ γνωρίζω ἀπὸ τὴν κόψη

  σὲ γνωρίζω ἀπὸ τὴν ὄψη
  ποὺ μὲ βία μετράει τὴ γῆ.

  ᾿Απ᾿ τὰ κόκκαλα βγαλμένη

  καὶ σὰν πρῶτα ἀνδρειωμένη
  χαῖρε, ὦ χαῖρε, ᾿Ελευθεριά!

  From a speech of Demosthenes in the 4th century BC:

  Οὐχὶ ταὐτὰ παρίσταταί μοι γιγνώσκειν, ὦ ἄνδρες ᾿Αθηναῖοι,
  ὅταν τ᾿ εἰς τὰ πράγματα ἀποβλέψω καὶ ὅταν πρὸς τοὺς
  λόγους οὓς ἀκούω· τοὺς μὲν γὰρ λόγους περὶ τοῦ
  τιμωρήσασθαι Φίλιππον ὁρῶ γιγνομένους, τὰ δὲ πράγματ᾿
  εἰς τοῦτο προήκοντα,  ὥσθ᾿ ὅπως μὴ πεισόμεθ᾿ αὐτοὶ
  πρότερον κακῶς σκέψασθαι δέον. οὐδέν οὖν ἄλλο μοι δοκοῦσιν
  οἱ τὰ τοιαῦτα λέγοντες ἢ τὴν ὑπόθεσιν, περὶ ἧς βουλεύεσθαι,
  οὐχὶ τὴν οὖσαν παριστάντες ὑμῖν ἁμαρτάνειν. ἐγὼ δέ, ὅτι μέν
  ποτ᾿ ἐξῆν τῇ πόλει καὶ τὰ αὑτῆς ἔχειν ἀσφαλῶς καὶ Φίλιππον
  τιμωρήσασθαι, καὶ μάλ᾿ ἀκριβῶς οἶδα· ἐπ᾿ ἐμοῦ γάρ, οὐ πάλαι
  γέγονεν ταῦτ᾿ ἀμφότερα· νῦν μέντοι πέπεισμαι τοῦθ᾿ ἱκανὸν
  προλαβεῖν ἡμῖν εἶναι τὴν πρώτην, ὅπως τοὺς συμμάχους
  σώσομεν. ἐὰν γὰρ τοῦτο βεβαίως ὑπάρξῃ, τότε καὶ περὶ τοῦ
  τίνα τιμωρήσεταί τις καὶ ὃν τρόπον ἐξέσται σκοπεῖν· πρὶν δὲ
  τὴν ἀρχὴν ὀρθῶς ὑποθέσθαι, μάταιον ἡγοῦμαι περὶ τῆς
  τελευτῆς ὁντινοῦν ποιεῖσθαι λόγον.

  Excerpt from a poetry on The Romance of The Three Kingdoms (a Chinese
  classic 'San Gua'):

  [----------------------------|------------------------]
    ๏ แผ่นดินฮั่นเสื่อมโทรมแสนสังเวช  พระปกเกศกองบู๊กู้ขึ้นใหม่
  สิบสองกษัตริย์ก่อนหน้าแลถัดไป       สององค์ไซร้โง่เขลาเบาปัญญา
    ทรงนับถือขันทีเป็นที่พึ่ง           บ้านเมืองจึงวิปริตเป็นนักหนา
  โฮจิ๋นเรียกทัพทั่วหัวเมืองมา         หมายจะฆ่ามดชั่วตัวสำคัญ

  Proverbs in the Amharic language:

  ሰማይ አይታረስ ንጉሥ አይከሰስ።
  ብላ ካለኝ እንደአባቴ በቆመጠኝ።
  ጌጥ ያለቤቱ ቁምጥና ነው።
  ደሀ በሕልሙ ቅቤ ባይጠጣ ንጣት በገደለው።
  የአፍ ወለምታ በቅቤ አይታሽም።
  አይጥ በበላ ዳዋ ተመታ።
  ሲተረጉሙ ይደረግሙ።
  ቀስ በቀስ፥ ዕንቁላል በእግሩ ይሄዳል።
  ድር ቢያብር አንበሳ ያስር።
  ሰው እንደቤቱ እንጅ እንደ ጉረቤቱ አይተዳደርም።
  እግዜር የከፈተውን ጉሮሮ ሳይዘጋው አይድርም።
  የጎረቤት ሌባ፥ ቢያዩት ይስቅ ባያዩት ያጠልቅ።
  ሥራ ከመፍታት ልጄን ላፋታት።
  ዓባይ ማደሪያ የለው፥ ግንድ ይዞ ይዞራል።
  የእስላም አገሩ መካ የአሞራ አገሩ ዋርካ።
  ተንጋሎ ቢተፉ ተመልሶ ባፉ።
  ወዳጅህ ማር ቢሆን ጨርስህ አትላሰው።
  እግርህን በፍራሽህ ልክ ዘርጋ።
