Sitelen Pona: U+F1900 - U+F19FF

Updated proposal by jan Tepo, 2022-01-31 and jan Lepeka, 2022-05-20

Sitelen Pona is a logographic writing system used to write the constructed language Toki Pona. Both the language and the script were created by Sonja Lang and are documented in her book, Toki Pona: The Language of Good. The section of the book describing the logography and used as a source for this proposal is made available to the public under the CC0 1.0 Universal Public Domain Dedication (as specified on page 3 of the German edition, Toki Pona: Die Sprache des Guten).

The 2014 book includes 120 words in its dictionary and assigns each one a logograph. In 2021, Sonja Lang published the Toki Pona Dictionary, a collection of common phrasings for English words collected from community surveys. The survey responses included a number of community-created words not included in the original book; 17 of these were found to be in common use and designated nimi ku suli (important words from the Toki Pona Dictionary). They are generally accepted as part of the language and the community has designed logographs for them.

This proposal includes a code point for each word in Toki Pona: The Language of Good and each nimi ku suli, as well as a few other words that appear in many existing fonts.

The script has several features for formatting and combining glyphs:

Foreign names are written in the logography using a rebus-type system in a cartouche. Inside a cartouche, each glyph represents the first letter of the corresponding word. For example:

The cartouche is encoded using two code points for the start and end, F1990 SITELEN PONA START OF CARTOUCHE and F1991 SITELEN PONA END OF CARTOUCHE, analogous to an opening and closing parenthesis. Fonts that implement this script should include OpenType features which add lines above and below any logographs that appear between these two code points, giving the cartouche the enclosed appearance that can be seen above. Here is an example template for such a feature:
```
@spIdeograph = [uF1900 ...];
@spCartouche = [uF1900.cartouche ...];

feature calt {

  # extend cartouches across ideographs to the right
  lookup spCartoucheForward {
    sub [uF1990 uF1992 @spCartouche] @spIdeograph' by @spCartouche;
  } spCartoucheForward;

  # extend cartouches across ideographs to the left
  lookup spCartoucheBackward {
    rsub @spIdeograph' [@spCartouche uF1991] by @spCartouche;
  } spCartoucheBackward;

} calt;
```
For fonts or environments without OpenType support, a combining character, F1992 SITELEN PONA COMBINING CARTOUCHE EXTENSION, which adds lines above and below the previous glyph, has also been included; however, its use is discouraged.
The word pi, which groups modifiers, can be written as a “long pi,” which appears under the modifiers being grouped. For example:

The long pi is encoded using F194D SITELEN PONA IDEOGRAPH PI followed by a zero-width F1997 SITELEN PONA START OF LONG GLYPH character. The end of the long pi is indicated by a corresponding F1998 SITELEN PONA END OF LONG GLYPH character. Fonts that implement this script should include OpenType features which add the extension under any logographs that appear between the two “long glyph” codepoints, as well as substitute the normal pi with a long pi if necessary. Here is an example template for such a feature:
```
@spIdeograph = [uF1900 ...];
@spExtension = [uF1900.extension ...];

feature calt {

  # replace pi + start of long glyph with pi extended to the right
  lookup spLongPi {
    sub uF194D' uF1997 by uF194D.extended;
  } spLongPi;

  # extend long glyphs across ideographs to the right
  lookup spExtensionForward {
    sub [uF1997 uF1999 uF199A @spExtension] @spIdeograph' by @spExtension;
  } spExtensionForward;

  # extend long glyphs across ideographs to the left
  lookup spExtensionBackward {
    rsub @spIdeograph' [@spExtension uF1998 uF199B] by @spExtension;
  } spExtensionBackward;

} calt;
```
For fonts or environments without OpenType support, the long pi may be encoded using a F1993 SITELEN PONA START OF LONG PI character in place of F194D SITELEN PONA IDEOGRAPH PI and a combining character, F1994 SITELEN PONA COMBINING LONG PI EXTENSION, that adds the extension under the previous glyph. However, encoding the long pi this way is discouraged.

Several other words can be written in a similar way to long pi, with related words grouped by an underline extending from the head word. For example:

Similar to long pi, these are encoded by following the head word with the F1997 SITELEN PONA START OF LONG GLYPH character and ending the sequence of related words with the F1998 SITELEN PONA END OF LONG GLYPH character. For groups of related words appearing before the head word, two other zero-width characters, F199A SITELEN PONA START OF REVERSE LONG GLYPH and F199B SITELEN PONA END OF REVERSE LONG GLYPH, are used in a similar manner.

Fonts that implement this script should include OpenType features which add the extension under any logographs that appear between two “long glyph” codepoints, as well as substitute the head word with a variant which lines up with the extension (to the right if followed by F1997 and/or to the left if preceded by F199B). Here is an example template for such a feature:

@spIdeograph = [uF1900 ...];
@spExtension = [uF1900.extension ...];

# ideographs that can be made long on both sides; F1908, awen, for example
@spDualExtendable = [uF1908 ...];
@spDualExtendedNormal = [uF1908.extended ...];
@spDualExtendedReverse = [uF1908.revextended ...];
@spDualExtendedBoth = [uF1908.dualextended ...];

# ideographs that can be made long on the right side; F1969, tawa, for example
# make sure to include @spDualExtendable and @spDualExtendedReverse as well!
@spExtendable = [uF1969 ... @spDualExtendable @spDualExtendedReverse];
@spExtended = [uF1969.extended ... @spDualExtendedNormal @spDualExtendedBoth];

# ideographs that can be made long on the left side; F1916, kama, for example
# make sure to include @spDualExtendable and @spDualExtendedNormal as well!
@spReverseExtendable = [uF1916 ... @spDualExtendable @spDualExtendedNormal];
@spReverseExtended = [uF1916.revextended ... @spDualExtendedReverse @spDualExtendedBoth];

feature calt {

  # replace ideograph + start of long glyph with glyph extended to the right
  lookup spExtensionNormal {
    sub @spExtendable' uF1997 by @spExtended;
  } spExtensionNormal;

  # replace end of reverse long glyph + ideograph with glyph extended to the left
  lookup spExtensionReverse {
    sub uF199B @spReverseExtendable' by @spReverseExtended;
  } spExtensionReverse;

  # extend long glyphs across ideographs to the right
  lookup spExtensionForward {
    sub [uF1997 uF1999 uF199A @spExtension] @spIdeograph' by @spExtension;
  } spExtensionForward;

  # extend long glyphs across ideographs to the left
  lookup spExtensionBackward {
    rsub @spIdeograph' [@spExtension uF1998 uF199B] by @spExtension;
  } spExtensionBackward;

} calt;

For fonts or environments without OpenType support, the extension may be encoded using a combining character, F1999 SITELEN PONA COMBINING LONG GLYPH EXTENSION, which adds the extension under the previous glyph. (Direct access to the glyph variants of the head word will also be needed in this case, but the encoding of these is up to the font designer.) However, encoding long glyphs this way is discouraged.

Adjacent glyphs representing noun phrases may be combined into a single glyph. For example:

This may be accomplished using a zero-width joiner. If more control is desired over the composition of the glyph components, F1995 SITELEN PONA STACKING JOINER or F1996 SITELEN PONA SCALING JOINER may be used in place of a zero-width joiner. F1995 SITELEN PONA STACKING JOINER specifies that the second glyph should be stacked on top of the first glyph, and F1996 SITELEN PONA SCALING JOINER specifies that the second glyph should be scaled and placed inside the first glyph. It is up to the font designer to decide which composite glyphs to support. Here is an example of how this may be achieved using OpenType ligatures:
```
feature liga {

  lookup spCompositeGlyphs {

    # using zero-width joiner
    sub uF1914 uni200D uF1928 by uF1914_uF1928; # kala lili
    sub uF196C uni200D uF1954 by uF196C_uF1954; # toki pona

    # using stacking and scaling joiners
    sub uF1914 uF1995 uF1928 by uF1914_uF1928; # kala lili
    sub uF196C uF1996 uF1954 by uF196C_uF1954; # toki pona

  } spCompositeGlyphs;

} liga;
```
