Description Aleksandr Andreev 2017-12-24 18:25:44 UTC
LibreOffice does not appear to provide correct support for Glagolitic (Unicode blocks U+2C00 to U+2C5F and U+1E000 to U+1E02F). The following is not supported:

1. No support for OpenType positioning (see picture).

2. Cannot switch the lettercase for Glagolitic characters.

Tested on Linux Mint 17 (Qiana), Version:

Steps to Reproduce:
1. See attached file with Glagolitic text.
2. Glagolitic font may be donwloaded from here:

Actual Results:  
1. Combining letters and diacritics not positioned correctly
2. Casing of lowercase to uppercase does not work.

Expected Results:
1. Diacritics and combining letters should be positioned correctly.
2. Cases should be cycled.

Reproducible: Always

User Profile Reset: No

Comment 5 Aleksandr Andreev 2018-01-03 04:34:50 UTC
Looks like the patch also fixes the OpenType positioning issues for Glagolitic (see attached), so perhaps this can be now marked Resolved?

Looks like glyph positioning is now fine. However, converting Glagolitic lowercase to uppercase does not work in Version:
