Tk Source Code

I'm using IDLE (with Python 3.4.3 and Tk version 8.6.1). The OS is Ubuntu 14.04 LTS. When I open the IDLE, everything works fine, until I open a .py file, or save a .py file, or click any menu in IDLE. Then the characters ´`~^ and characters with accents, like á, à, â, ã doesn't work anymore. I found the Issue 25356 at [https://bugs.python.org/issue25356] and ask for help, but no one answer me. These characters are dead keys in Brazilian keyboards: if I want the "á", first I press "´" key, then I press "a" key, then the "á" character appears at the window. I found that the diaeresis key shows this bug in the same way. In Brazilian Portuguese there was diaeresis over "u" character (like "ü") until few years ago in words like "freqüência" (frequency), now we don't use it anymore, except for names (like "Müller").

A pure-Tcl/tk script (or procedure) reproducing the issue would help.

But I think this problem be more likely in the way Linux handles those keys given the physical keyboard layout you have. In other words: I will probably not be able to reproduce.

Finally, does this ticket ring a bell for you perhaps? Any similarity?
