Public bug reported: I recently noticed a regression in how LibreOffice Writer handles font substitutions for basic ASCII punctuation including space (U+0020). For test purposes, I wrote a document in the Old Hungarian script and used a font called "OldHungarian" from https://github.com/OldHungarian/old- hungarian-font to display the text. The font is designed to cover only the characters in the Old Hungarian block (U+10C80 to U+10CFF) plus a couple of punctuation marks that might not be available in all fonts such as ⹁ (U+2E41 REVERSED COMMA) and ⹂ (U+2E42 DOUBLE LOW-REVERSED-9 QUOTATION MARK). The font doesn't include glyphs for anything else such as basic Latin letters or Latin punctuation.
Normally, LibreOffice is supposed to find substitute glyphs for characters that are not included in the current font but for some reason it fails to do so with the OldHungarian font for all the basic punctuation from U+0020 (SPACE) to U+002F (SOLIDUS), U+003A (COLON) to U+0040 (COMMERCIAL AT) and U+007B (LEFT CURLY BRACKET) to U+007E (TILDE). Latin letters a-z and A-Z as well as numbers 0-9 work fine. See the attached screenshot, where I've included a sentence in English in the middle of Old Hungarian text and set OldHungarian as the font for the whole selection. English letters show up ok as well as spaces in between them. Spaces and punctuation between words in the Old Hungarian script show up as boxes. I don't use Old Hungarian on a daily basis, so I don't know exactly when this regression happened but I'm sure things worked as expected when I submitted bug #1804657 https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1804657 for 6.1.3.2 (installed as a snap). Now the problem occurs on both 6.0.7.3 installed from Ubuntu 18.04 repositories and on 6.3.2.2 installed as a snap from the stable channel (relase 151).
