Fix arabic font mono keepass

[ghost]

Hello .. as you see in screenshot the arabic text displayed in reversed and seperated way ...

Even if i change font .. (most of them show arabic as rectangle) .

You can copy this sample text for quick test ... and also copy it to any text editor (leafpad,kwrite,gedit,kate) to see how should text look like OR as you see here is right ... :

Sample Text:{

I also test it on kubuntu 18.04 with mono version 6 ... same result.

If i run keepass from command line with terminal like this: (mono "/mnt/shared/KeePass.exe") no log or problem ...

The KeePass developer say : "KeePass in Windows seems to handle the font correctly, so it seems likely the mono font selection doesn't work correctly."

It is not font selection but text shaping. On linux, you need to have at least some Arabic fonts installed first. One of google noto Arabic fonts should be available on Ubuntu 18.x. Mono 4.6 is maybe 5 years old? Your messages says 2014... Anyway, besides having at least one Arabic fonts, you need to have a text shaping engine that understands Arabic. On windows, that's uniscribe. On mac os x, it is coretext, on linux that's harfbuzz.

I think recent mono (5,6...) can use coretext on mac os x, but I am quite sure mono on linux does not yet use harfbuzz. Pango (which mono may or may not use) on linux is quite limited in Arabic capabilities.

Is that mean there is no hope or workaround ?

Here is another test with Lubuntu 20.04
I installed these packages with synaptic:

• libharfbuzz-bin 2.6.4
• libpango-1.0-0 1.44.7 and libpangocairo-1.0-0 1.44.7 <<< are already installed
• fonts-sil-scheherazade 2.100 <<< Arabic support font
• mono-complete version 6.8

Then i opened mono/KeePass ,changing font ... and got same result.

Another test ... i installed current latest wine-mono-5.1.1-x86.msi with wine ..... and run it (:~$ wine /path/to/keepass.exe)
And it's works!

But then i am facing another issues ....

1.first ...... whereas they work with mono complete, plugins cannot be loaded because according to different sources the easiest way to make plugins work is installing mono-complete and wine-mono-5.1.1 seems not equal to mono-complete !

2.second ...... cannot render color format of entries whereas it's works with mono-complete ...

3.third ....... if i add and enable Arabic.lngx language for the UI .. there is a lot of bugs should be fixed ... this screenshot explain :

4. when i close program i got this log in terminal , i don't knew if related or not ...

Wine-mono uses wine's gdiplus, which probably uses wine's usp10 (uniscribe) eventually. Mono on linux uses libgdiplus which is less complete, I think.

Wine-mono is quite different from mono. You might find something intermediate by using win32/win64 mono under wine instead of wine-mono; and you might be able to improve on wine-mono's behavior by using genuine Microsoft gdiplus via winetricks. And lastly, you might also get something else running genuine Microsoft dotnet under wine...

I remember that before months i tested installing dotnet framework 4.x under wine and keepass worked but suddonly crush if i press something so unusable ...
.............
The new test here is installing current latest "mono-6.12.0.98-gtksharp-2.12.45-win32-0.msi" under wine after uninstalling wine-mono ....
now if i run like this:

2020@2020:~$ wine "/media/sf_shared/exe TesTs/KeePass-O/KeePass.exe"
0009:err:mscoree:CLRRuntimeInfo_GetRuntimeHost Wine Mono is not installed

will not work .. i have to run it like this:

2020@2020:~$ wine "/path/to/.wine/drive_c/Program Files (x86)/Mono/bin/mono.exe" "/path/to/KeePass-O/KeePass.exe"

Color format of entries will work ... but these the issues .....

1.first ..... cannot recognize that there is plugins and languages files at all ... will not loading them without any error message.

2.second ..... Arabic text will rendered but in buggy way .... at first will be reversed then if i moved the slide of entry view will be fixed then if i moved again the slide of entry view will text will be mixed some lines reversed and some lines right ....
