Description chvracop 2021-11-26 22:51:33 UTC
Description:
The following bug happens at the begining of a sentence, paragraph when font Calibri is used.
When there are 2 greek Capital letters and a space between them the polytonic marks disappear. They exist, though not appearing or printing.

Example: "Ὁ Ἰησοῦς"
Greek marks dasia and psili do not appear.

If there are two or more spaces between the words though, they appear.

Steps to Reproduce:
1. Paste to the writer the phrase "Ὁ Ἰησοῦς" and select it.
2. Change the font to Liberation Serif. The marks appear.
3. Change the font to Calibri. The marks disappear.

Actual Results:
Ο Ιησοῦς

Expected Results:
Ὁ Ἰησοῦς


Reproducible: Always


User Profile Reset: Yes



Additional Info:
Font Calibri is the default microsoft font but someone may have many documents on that font created with Microsoft Word and recently migrated to LibreOffice or want to use both like myself.

| I can reproduce it but only with Calibri (v6.23) and Carlito
| (v1.103: Beta1) (Carlito is usual substitute for Calibri) fonts.
| All other fonts I tried, including Arial, Times New Roman, Verdana
| and some open source fonts act normally. It is beginning to look
| like a bug in those two fonts.

| Adobe Illustrator CS5 has the same problem.

FWIW, even notepad.exe has the same problem (marks disappear for "Ὁ Ἰησοῦς", and re-appear when an extra space is added) with Calibri font on Windows 10.

I confirm the notepad bug. So now we can report that to microsoft. Could someone report it?

Stephane, not our bug?

This is how the font is designed, when two capital Greek letters are next to each other or separated by space, they both loose their accents.
