Summary0024750: Accents in GTK2
DescriptionPatch for issues 0024693, 0015688, 0015688, 0022507 etc.
In some situations, accented characters are duplicated when typing: 'áá', 'éé'...
It seems too frequent when the input language is latin-derived: Portuguese, Spanish, etc.
Because not all systems need this correction, I have implemented it via a compilation directive (Mattias Gaertner suggestion). It will be necessary to include a -dGtk2LatinAccents in the compiler parameters.
TagsNo tags attached.
Fixed in Revisionr42102, r42581

I applied the patch in r42102. Thanks.
Accented chars still work in my environment with TEdit and TMemo. Nothing broke there.
SynEdit dropped on a form did not get accented chars at all. ' + "a" gives just "a". No change there either.
However the source editor in Lazarus behaves differently. Earlier I got accented chars with red color which is also wrong. Now I don't get accent but the color is normal.

I hope the SynEdit / source editor issue will be solved. Maybe it is a separate issue.

Please test everybody.

Éderson Cássio, you can attach a patch also to an existing bug report. Now there are many duplicates. No big deal of course ...

I have the intention to verify SynEdit soon, maybe next week (because this week I'm full of work, which I'm doing in Lazarus :D)

Actually, I'm programming under Windows, where I have no problems with accents. I open the projects under Linux only to compile them.

What must I do to document the new compiler directive, for others who have the same problem?

No need to really document it because it is a temporary define for testing purposes.
You can advertise it as you wish, for example by personal email, mailing list and forum.

Apparently it works as nobody complained. I removed the define Gtk2LatinAccents.

This created problems after all. See mail thread at Lazarus list:
 IDE - SynEdit not accept accented characters / revision found

I reopen and detach myself from this issue. I don't know how to fix it except for reverting commits.
