Building

Fonts are built automatically by GitHub Actions - take a look in the "Actions" tab for the latest build.

If you want to build fonts manually on your own computer:

• make build will produce font files.
• make test will run FontBakery's quality assurance tests.
• make proof will generate HTML proof files.

The proof files and QA tests are also available automatically via GitHub Actions - look at https://notofonts.github.io/soyombo.

For information on how to work on Noto fonts, how the build process works and how to maintain it, see the README file of the notofonts.github.io repository

Font Version

2.001

OS name and version

MacOS 14.3

Application name and version

Safari 17.3
Firefox 122.0

Issue

An explicit U+25CC DOTTED CIRCLE is deleted before all vowel signs, vowel modifiers, and final consonants. This is in addition to the gemination mark, which has already been reported as issue #2.

To reproduce, go to
https://lontar.eu/en/notes/encoding-orders-of-brahmic-scripts/index.html#Soyombo
and check the rows VOWEL_ABOVE, VOWEL_BELOW, VOWEL_POST, VOWEL_MOD_ABOVE, VOWEL_MOD_POST, CONS_FINAL_BELOW.

Expected result: Each mark in these rows should be attached to a dotted circle, as each one is prefixed in the text with U+25CC.

Observed result: Each mark is rendered without a dotted circle.

Date: 2020-03-28

Font version

Version 2.000

Issue

A gemination mark makes the vertical bar of a single consonant shorter than normal height of the vertical bar on a standalone consonant. L2/15-004R §§ 4.14.2–3 describe how the vertical bar can become longer than the default, but not shorter.

Font Version

2.000

OS name and version

W10 20H2, but probably all OS

Application name and version

Qt 6.2.0, but probably all apps

Issue

1. Type 25CC dotted circle + any umlaut
2. You see umlaut
3. You should see umlaut planted on 25CC
4. Done by ligature substitution w/o any specific OT feature (not liga, not rlig…)

Character data

U+25CC dotted circle
U+11A51 Soyombo vowel sign I …………… U+11A5B Soyombo vowel Length mark
U+11A8A Soyombo final consonant sign G ……………… U+11A99 Soyombo subjoiner

A few more fixups to Soyombo

1. On 25CC (dotted circle) move top anchors to the right, they should be over the top dot.
2. On 25CC (dotted circle) move bottom anchors down to bottom line and to the right.
3. Add 'kern': gemination & 25CC = −660
4. I really dunno what to do with 25CC+subjoiner. But because it is a virtual virama and should not be in normal text, I’ve just moved subjoiner’s anchors down and to the right. Maybe you’ll coin a better way.

(OpenType is so fragile, hope I did not affect any of font’s functionality.)
