This is not an FPC or Lazarus bug at all, but a system wide keyboard setting that enables complex characters to be composed by combining keystrokes. You can
- Either turn that off
- Or hit space before you type the A
I checked this on Windows, but this feature is also available for Linux in some configurations.

Can you try Thaddy's suggestions.

If I understand them, I'll surely give it a try. I'll consult linux guru's on the first one. With respect to the second one: I don't want to type an A, I just want to type string quotes.

Ah, now I understand what you mean: 'dead keys'. Dead keys are enabled but this is not the point. If I hit ' (single quote) then IMMEDIATELY A´ (A followed by accent acute) is displayed. The cursor is located between both characters.
I don't get this behavoir with win xp 32 on the same machine, nor do I get it with other editors like this one or gnome's text viewer.

This problem was discussed on the Lazarusforum (
It is on the Road to 1.0 also (, and Mattias seems to be responsible for this feature.

As for now turning dead keys off if you work in the Lazarus IDE seems the way to work around it (you can toggle this in a simple shell script).

This seems to have been fixed in the mean time (tested with Laz 0.9.29 r22953/fpc 2.2.4 on Linux GTK2)?
Elphi, can you retest and report back?

I've abandoned the x86_64 platform, so I can't test it.

Then I resolve the issue.
