Unicode Range

[ayuhito]

We've been supporting the DSEG fonts at Fontsource for a while and I've been wondering if you could provide the values for the CSS unicode-range selector? That would be super useful for the project and users downstream.

Thanks!

Using BabelMap Online (and the desktop version), I see that DSEG7ClassicMini-Regular.ttf has exactly 95 glyphs, all in

• Plane 0 : Basic Multilingual Plane (BMP)
• Block 0 : [Basic Latin] [0000..007F] (95 characters).

Surprisingly, BabelMap Online reports fewer Unicode glyphs for DSEG7Classic-Regular.ttf (although one glyph in another block).

BabelMap Online is a new tool for me, so please double-check my work!

Suggestion: The DSEG7 fonts should have Unicode encoding for the seven-segment digital numerals in the (2020) Unicode 13.0 block Symbols for Legacy Computing from 1FBF0 to 1FBF9.

Besides having encoding for the Latin block, DSEG7 could have parallel Unicode encoding for letters in this PUA-A Seven-Segment Display Patterns (which include other symbols besides the alphabet).

While seven-segment English letters have not been encoded as part of the Unicode standard, 7-segment letters have been designated in a reserved Unicode block, Supplementary Private Use Area-A, by three typefaces.

The PUA-A glyphs from FF700 to FF7FF are designated Seven-Segment Display Patterns by the SIL-OFL typefaces

1. Fairfax HD and
2. Nishiki-Teki.
   These PUA-A glyph designations have also been reserved (for possible implementation in the future) by a third font,
3. Catrinity.

These 3 typefaces have coordinated PUA designations (also via the Under-ConScript Unicode Registry, UCSUR).

Hi, you can try the version v0.50beta1, which added supports to U+1FBF0 ~ U+1FBF9 plus various other codepoints, including arrows, kana and all combinations of segments (see #33 (comment)).
