[Please move this to a different component if applicable, I'm not sure where the editor comes from.] It is impossible to insert the "ę" or "Ę" characters (latin letter "e"/"E" with ogonek) from keyboard when editing in Module: namespace with the code editor on the Polish Wikipedia. "ę" is inserted on the Polish keyboard using AltGr+e (aka Ctrl+Alt+e). If the editor uses this as a hotkey, it shouldn't (nor should it use any other Ctrl+Alt combinations). (Reported at https://pl.wikipedia.org/wiki/Wikipedia:Kawiarenka/Kwestie_techniczne#VisualEditor_a_polskie_diakrytyki)
You want CodeEditor. I note that I can type ę and Ę fine in CodeEditor from here, where the key combinations are "<Compose> ; e" and "<Compose> ; E". I also remapped Ctrl+Alt+E to "ę" temporarily, and I was able to enter that character using that key combination in CodeEditor on a module page on plwiki with no issues (using Firefox 24 on Linux).
@Brad, depending on how exactly you remapped it, the Ctrl+Alt+E might be mapped to "ę" in some lower-level layer, not letting the browser even see it. (I used this a few times to wrestle with some stupid applications which take Ctrl+Alt shortcuts for themselves to take it away from them.) Some grepping shows ACE Editor uses "Ctrl-Alt-E" / "Command-Option-E" for the "togglerecording" command. This is most likely the culprit. This seems to be the only Ctrl-Alt shortcut involving regular letters (there are also a few with arrow keys and backspace).
In that case, it looks like you could follow the example in modules/jquery.codeEditor.js near line 151 to disable this command too.
These are all the default defined key combinations: https://github.com/ajaxorg/ace/blob/40ea516801332fb8e96f8ba2e5046eece2fd95d3/lib/ace/commands/default_commands.js
