Summary0007742: SynEdit cannot write accent chars even with font.CharSet = UNICODE
DescriptionIf I use SenEdit in either gtk1 or gtk2 and set it's font.charset to UNICODE (had to find out it's 4 btw, where is the constant defined?) I can read UTF-8 files ok, I can also write all chars which don't require a "accent" key.

Let me explain:

If you wish to write eg: á (should look like a with small ' above)
You can either write it using one prepared key in slovak keyboard (where 8 is on the non-numpad) OR write the "´" (should be that small thing) and THEN press normal "a".

It's not a big problem where the choice exists, but not all accented chars are available on the keyboard. I'm sure other languages have such thing too.

In gtk1 I get the "a" and "´" as 2 separate chars if I try to write with 2 keys.
In gtk2 I get only normal "a".
Steps To ReproduceSet SynEdit.Fond.Charset to 4 (UNICODE) and try to write accented chars via the accent modifier keys.
TagsNo tags attached.

Vincent corrected me on the gtk1 problem with dead keys.

But with gtk2 this is still a bug.

Thanks for adding additional information for this bug.

After Windows Unicode, this bug is the biggest problem for full Unicode support on Lazarus.

Now it is a gtk 1 only bug.

It does not work for me in GTK2, SVN Rev 14640.
I have a Swiss German Keyboard $LANG=de_CH.UTF-8

For ex. I'd like to write a "â" like in Château.
Two problems:
1: When testing with Keyboard events on a Form or Synedit, UTF8KeyPress is never called (see below)
2: When typing in a TEdit or TMemo etc. the correct character appears but twice (ââ)

Testing all Keyb. events on a form with writeln returns this:

--- Hit the "^" Key
KeyDown 146
KeyUp 146
--- Hit the "a" Key after this-> No UTF8Keypress event. Keypress has normal "a"
KeyDown 65
KeyPress a
KeyUp 65
--- Hit the "a" Key again -> TF8Keypress event with normal "a"
KeyDown 65
UTF8KeyPress a
KeyPress a
KeyUp 65

The "â" is not so important for the source editor, but it's the same problem for "^". I can't type this char in GTK2 IDE but I can paste it from CB.

@Felipe: I don't think 0011045 is closely related. It's, as you say, rather trivial that different source file encodings cause some trouble.

I will sum up the observations for my system:

GTK1: TSynedit -> '^' appears immediately (does not act as a dead key)
GTK1: TMemo -> '^' appears (acts like a dead key) everything fine!
GTK2: TSynedit -> '^' nothing appears, but blocks the UTF8Keypress event of the next keystroke. (see above)
GTK2: TMemo -> '^' appears, acts like a dead key but inserts the char twice.

Other GTK2 based Apps work as expected on my System

I think this has been fixed in the meantime, with LCL now fully supporting UTF8?

No feedback from reporter.
Seems to be fixed in the meantime.
Please test and close if fixed, or re-open if issue remains.
