Unicode 25D2 "Circle With Lower Half Black" and 25D3 swapped in DejaVu Sans and DejaVu Serif

[bitinerant]

The Unicode character 25D2 "CIRCLE WITH LOWER HALF BLACK" and 25D3 "CIRCLE WITH UPPER HALF BLACK" are swapped in most fonts, including major ones such as Arial, Times New Roman, and the Ubuntu fonts. The only fonts I could find which have it _correct_ are TakaoPGothic, Lucida Sans Unicode, FreeMono, FreeSans, FreeSerif, DejaVu Sans Mono, and Arial Unicode MS.

The official Unicode description for these characters can be found at http://www.unicode.org/charts/PDF/U25A0.pdf

CIRCLE WITH LOWER HALF BLACK (U+25D2) and CIRCLE WITH UPPER HALF BLACK (U+25D3) in Sans and Serif are reversed. They should be swapped.

Font substitution obviously plays a big role here, and different applications have different rules for this. For example, OpenSymbol and Courier New both display incorrectly in Firefox but correctly in LibreOffice.

Affected packages include ttf-ubuntu-font-family and ttf-mscorefonts-installer. The packages xfonts-base and xfonts-scalable and others may also be affected.

From memory we don't have these two glyphs in the Ubuntu Font Family yet; would you be able to supply a screenshot so that we can try and work out where they're being substituted from and fix them in /that/ font.

[bitinerant (bitinerant)]

I can post a screenshot but I think it would be much more useful if it did not include the fonts which do not define U+25D2. Is there a way to search all fonts to see which ones define that character?

[Paul Sladen (sladen)]

Probably the easiest is to start gnome-character-map/gcharmap; select "Ubuntu", search to U+25D2 and then *right-click* on the glyph. This will then show a larger rendering of the glyph and state the _actual_ font that the glyph is coming from in the pop-up.

Depending on whether it's correct or not you can go through the list of other fonts and see which ones are swapped.

Thanks for the instructions. In the Ubuntu font, U+25D3 maps from DejaVu Sans. Same for Arial, Garamond, Lucida Sans, Microsoft Sans Serif, Ubuntu Mono, Ubuntu Condensed, and dozens of others I tested. Serif and Times New Roman map U+25D3 from DejaVu Serif. Most monospace fonts map from DejaVu Mono and are fine.

So it seems that the problem is with these two fonts:
  * DejaVu Sans
  * DejaVu Serif
