--- Comment #12 from Owen Genat <[email protected]> --- Created attachment 89111 --> https://bugs.freedesktop.org/attachment.cgi?id=89111&action=edit FontForge screenshots showing STIX-Regular and STIXMath-Regular. I would be concerned about including the STIX fonts in LO as they contain many invalid uses of code points. Where Unicode does not support a particular character the Private Use Area (U+E000..U+F8FF), Supplemental Private Use Area-A (U+F0000..U+FFFFD), and Supplemental Private Use Area-B (U+100000..U+10FFFD), can be used to encode 6400, 65534, and 65534 characters respectively. In v1.1.1-Word the STIX fonts include these invalid non-Unicode code points: - STIX-Bold, 63 glyphs, 0x110000..0x11003c - STIX-BoldItalic, 2 glyphs, 0x110000..0x110001 - STIX-Italic, 2 glyphs, 0x110000..0x110001 - STIX-Regular, 125 glyphs, 0x110000..0x11007c - STIXMath-Regular, 926 glyphs, 0x110000..0x11039d The Bold, BoldItalic, Italic, and Regular fonts all make partial use (~100-350 glyphs) of the Private Use Area, while the Math font does not use this area at all (attached screenshots are indicative). There are also some basic errors reported by FontForge. While I can appreciate the need for a greater range of math glyphs, pushing non-Unicode fonts of this nature into the LO user-base would seem potentially problematic and at the very least require *extensive* testing i.e., printing, PDF/file-embedding, interop, etc. The current OpenSymbol font by comparison, although less extensive, does not contain any errors or invalid encodings. -- You are receiving this mail because: You are the assignee for the bug.
