I am using a hungarian keyboard, on which the ";" and "*" characters are entered in combination with AltGr. When I start to add some new conde in fltk2, I see the followings:
Some characters (i.e. ß) with AltGr appear int the code window correct, some other (also with AltGr) (i.e. ;) does not appear int the code dialog window.
After closing the code window, in the main window, in the widget tree I can see some starnge characters on the place where I tried to insert the characters that didn't appear int the code window. The characters that appeared int the code window right, also appear right in this place.
When I write the .cxx file, all the characters on that place appear weired (mostly squares).
I also use fltk2 with a newer version of my distro (, the difference is (as much as I know) that the newer version is utf8 based. On the newer OS the wrong AltGr characters simply doesn't appear, but no weired characters are written.
With fltk-1.1.7 I have no problems.
Thank you for your great work!

This is a repeat of bug #1725:

It is not 100% clear to me the problem is related to intl. keyboards.
It seems to be an issue in the event system when you some control or alt combo (in my case, CTRL+arrows seems to keep the CTRL character around till the next key press, which will introduce the invisible character).
