greek fonts problems
Expected behavior
Greek characters should be used out of the box.
Observed behavior
I had problems writing greek by MText. Some fonts displayed diamonds instead and a font was partially succeeded. Probably there is a problem with the keyboard layout greek people use.
Operating System and LibreCAD version info
Opensuse tubleweed and librecad 2.2.0-1.4
Anyway, as i had mentioned in https://forum.librecad.org/greek-fonts-large-file-from-dwg-to-librecad-td5714230.html and in https://forum.librecad.org/Insert-text-in-greek-language-td5717563.html, i had solved the problem by editing the greeks.lff and unicode.lff files. I checked today and these files works fine, as long as i define their paths in preferences. Feel free to use them as you wish. I attach these files I edited. I didn't touched first lines, so Hershey Rallaz is mentioned as author of these as he should be. greeks-mine.lff.txt unicode-mine.lff.txt
(Obviously, remove .txt file extension)
mine_fonts.dxf.txt not_mine_fonts.dxf.txt In these dxf files appears all greek letters that my keyboard produce naturally. not_mine_fonts is created my librecad without setting special font path. On my laptop neither unicode.lff fonts can make them appear (at least in preview). mine_fonts is the same dxf after configuration of font path to use unicode-mine.lff. These time all possible greek letters appear properly in preview at my laptop.

Basically we have an issue with UTF/Unicode and ASCII codepage mapping.
The greek*.lfffiles contain only 8-bit ASCII code characters. They may work on non-UTF/Unicode systems, where the keyboard creates 8-bit codes for a defined system codepage.
Your unicode-mine.lff adds the missing greek UTF-8 characters, U0386 to U03d4, that's why this font works.
Sadly the original unicode.lff has got some improvement, so we can't simply pull yours into the repo. But your additions are clear and I can merge them manually into the latest unicode.lff.
Concerning the other greek*.lff fonts, we can probably apply the same changes from unicode.lff to make them work properly.
I just can't understand your changes in greeks-mine.lff yet, it needs a deeper look if there were some improvements in the deployed greeks.lff font too.

Today, i cannot remember how I managed to edit lff files. What i remember is that I firstly edited the greeks.lff file. greek fonts were there but corresponded to wrong keys for my keyboard layout. So, probably i used xev program and just rearranged fonts to my keyboard layout. The only true design from scratch was letter "ς" that corresponds to "w". After, that i merged the already existed greek letters to unicode.lff accordingly. Unfortunately, that is all I remember.
