Sample document to ilustrate Bug

Greek symbols has names according to Language in LibO, for example in Lithuanian I write %ALFA for Greek ALPHA letter. When I open that document in Writer with different Language, then that letter automatically is converted to correct name, f.e. if Language in LibO is English then after open and enter in to formula editor that name of Greek letter becomes %ALPHA. This OK.

 But this not apply to Italic Greek Letters. F.e. if I write %ivarfi (Lithuanian language) and open that document in Writer with English language then in formula editor (formula must be updated to see effect) mentioned name stays same %ivarfi.

 Attached sample document with Greek letters created in Writer with Lithuanian Language.

 I also can reproduce this with LibO v3.6.4.3

Thank you for reporting this issue! I have been able to confirm the issue on:
Platform: Bodhi Linux 2.2 x64

As you have confirmed the issue on an earlier release I am changing the version number as version is the earliest version that we can confirm the bug, we use comments to say that the bug exists in newer versions as well.

Marking as:

New (confirmed)

Normal - can prevent professional quality work

Low - the number of users affected by this one will be quite low, first off using insert -> formula is already quite rare (the vast majority of users use LibreOffice in a basic writing program), furthermore only an issue if you're using multiple languages. If another bugs are marked as a duplicate this will suggest others are also affected and may be a reason to up the priority.

Confirmed with LibO 4.4.0
It seems to be like this since the old times.

There is a pb when saving document, because symbols from Greek set or special set are correctly translated to English, but symbols from iGreek set are not translated.

Same thing occurs when opening document: symbol from iGreek set should be read in English, but they are read in the language of the UI. So for instance, %BETA is correctly read, but %iBETA is not read with French UI, as it is %iBÊTA which is expected.
Comment 3 Laurent Balland 2015-02-03 14:50:43 UTC
Resolution of this bug would be quite difficult, due to compatibility problems: all actual versions of OOo/LibO/AOO are expecting names of iGreek letters in the language of the UI. So, if LibO correctly saves them with their English name, all other versions of OOo/LibO/AOO won't be able to read the iGreek letters anymore.

As UI language is not stored in ODF file LibO could only try to guess, according to the language of the text if the formula is inserted in a Writer document for instance.

A solution may be to store the language of the UI into the math object. This information could be ignored by other versions of OOo/LibO/AOO, and can be used by LibO to correctly display iGreek letters.
Comment 4 Laurent Balland 2015-02-03 20:35:10 UTC
iGreek set was introduced in OOo 3.3.0 and LibO 3.3.0

Change version accordingly

Comment 16 ⁨خالد حسني⁩ 2023-09-21 10:35:19 UTC
This is now fixed but the file needs to be re-saved from the localized version first so that the English names of the symbols gets saved in the file.
