See the top-level README.md for installation instructions.
The latest release and all past releases are listed on the GitHub repository’s release page. Each release has ZIP files attached for Rawnd Musmus Duployan and Rawnd Musmus Duployan Uncow.
- All characters in the Duployan and Shorthand Format Controls blocks
- Non-Duployan characters used with Duployan, such as digits and punctuation
- Some custom (non-Unicode) extensions
Rawnd Musmus Duployan uses some code point sequences not sanctioned by Unicode to support some orienting letters needed in Chinook Jargon (and, incidentally, various other modes). Adding the sequence <U+034F, U+034F, U+034F> after one of the letters U+1BC44, U+1BC53, U+1BC5A, U+1BC5B, U+1BC5C, U+1BC5D, U+1BC5E, U+1BC5F, or U+1BC60 changes it from primary orientation to secondary orientation.
There are also some private use characters for non-joining characters:
- U+E001 LATIN CROSS POMMEE
- U+E003 HEART WITH CROSS
- U+E010 TWO LINES JOINED CONVERGING LEFT
- U+E011 LEFT PARENTHESIS WITH STROKE
- U+E012 RIGHT PARENTHESIS WITH STROKE
- U+E013 LEFT PARENTHESIS WITH DOUBLE STROKE
- U+E014 RIGHT PARENTHESIS WITH DOUBLE STROKE
- U+E015 STENOGRAPHIC SEMICOLON
- U+E016 STENOGRAPHIC QUESTION MARK
- U+E021 COMBINING DIGIT ONE ABOVE
- U+E02A COMBINING RING-AND-DOT ABOVE
- U+E031 COMBINING DIGIT ONE BELOW
- U+E033 COMBINING DIGIT THREE BELOW
- U+E035 COMBINING DIGIT FIVE BELOW
- U+E037 COMBINING DIGIT SEVEN BELOW
Every character is either joining or non-joining. Some joining characters are orienting. Most letters are joining. Most vowels are orienting and most consonants are not. Orienting characters have either primary or secondary orientation, which determines which way they curve (counterclockwise or clockwise) in any given context. Circles and curves have different rules for what primary orientation means. Secondary orientation is always the opposite of primary orientation.
If a primary circle appears between two letters that form a non-straight angle, it curves whichever direction puts it opposite the angle. Otherwise, it curves counterclockwise.
If a primary curve appears in medial or final position, it curves counterclockwise. In initial position, it curves clockwise.
Most curves are oriented relative to their preceding letters, if any, falling back to their following letters in initial position. Hooks (U+1BC7A DUPLOYAN AFFIX ATTACHED E HOOK and U+1BC7B DUPLOYAN AFFIX ATTACHED I HOOK) follow the opposite rule.
Letters are cursively joined to adjacent letters with contextually appropriate forms. This includes pseudo-cursive letters like U+1BC00 DUPLOYAN LETTER H and U+1BC80 DUPLOYAN AFFIX HIGH ACUTE which do not visually touch adjacent letters but which otherwise have cursive-like interactions with them.
Stenograms are separated by non-joining characters. This includes digits, symbols, punctuation, and most spaces. To separate stenograms with no extra space between them, use U+200C ZERO WIDTH NON-JOINER. To include a usually non-joining character in a stenogram (e.g. U+2E3C STENOGRAPHIC FULL STOP), join it to adjacent characters with a non-breaking space (U+202F NARROW NO-BREAK SPACE) or step (U+1BCA2 SHORTHAND FORMAT DOWN STEP or U+1BCA3 SHORTHAND FORMAT UP STEP).
Overlap trees are supported up to a width of 2, a depth of 2, and a breadth of 2. (See Unicode Technical Note #37, section “Shorthand Control level of implementation” for what those terms mean.) These are the maximums: not all letters have values that high. The font does not support U+1BCA1 SHORTHAND FORMAT CONTINUING OVERLAP followed by U+1BCA0 SHORTHAND FORMAT LETTER OVERLAP, which is syntactically valid but unattested.
Certain symbols have limited support for overlaps as used in Romanian:
- U+003C LESS-THAN SIGN
- U+003D EQUALS SIGN
- U+003E GREATER-THAN SIGN
- U+00D7 MULTIPLICATION SIGN
Secants are applied to their preceding letters, except for initial secants, which are applied to their following letters.
The vertical positioning of a stenogram is based on its first visually prominent character, which is placed on the baseline. Different modes of Duployan have different conventions for vertical positioning, but the precise positioning is not significant.
Most letters support shading via U+1BC9D DUPLOYAN THICK LETTER SELECTOR. It is unsupported for some letters for which shading is not attested. Although shading is attested for orienting letters, that is not yet supported.
Some common punctuation marks may be circled in Romanian to disambiguate them from similar-looking letters. Add U+20DD COMBINING ENCLOSING CIRCLE after the punctuation for this circle.
Digits support fractions (with U+2044 FRACTION SLASH), superscripts (with the OpenType feature 'sups'), and subscripts (with 'subs').
Rawnd Musmus Duployan supports all modes mentioned in the Duployan Unicode proposals:
- Duployé’s original mode (French)
- Pernin (English)
- Perrault-Duployan (English)
- Romanian Duployan
- Sloan-Duployan (English)
- Stenographie Duployé codifiée (French)
- Wawa Shorthand (primarily Chinook Jargon, English, and French, but also Comox (Sliammon), Halkomelem, Latin, Lillooet, Okanagan, Sechelt, Shuswap, Squamish, and Thompson)
The character set available in Unicode is not actually sufficient for any of these modes, but this font supports what it can, with a few non-Unicode extensions for Chinook Jargon.
Rawnd Musmus Duployan does not work in all applications. For proper shaping, it requires HarfBuzz 8.1.0 or later, which is used in all major browsers on all operating systems, and for most applications on Linux. Even in some applications that use HarfBuzz, though, it is broken to varying degrees. If the main font does not work, use Rawnd Musmus Duployan Uncow as a fallback.
In particular, long strings are liable to be rendered wrong. The glyphs will not be cursively connected but will instead overlap each other in a semilegible jumble. This is because HarfBuzz has an internal limit of how many operations it will take for a buffer before giving up. Splitting long paragraphs into multiple paragraphs works around the problem. Inserting a character not supported by the font in the middle of paragraph also works.
Rendering any significant amount of text in the main font is noticeably slow. A web page with around 1000 words in Duployan can take over 30 seconds to load.
