Wide (UTF-8) characters cannot be input at start of a line

Reported by: rjray Owned by:
Priority: major Milestone:
Component: Multilingual Input Method Editor Version: 0.51
Keywords: Cc:


While editing a file that has both straight ASCII (English) and UTF-8 (Russian) content, I found that if the cursor was at the start of a line, I could not enter any of the Russian characters. If I switched the keyboard back to the US layout and typed a character, or typed a non-wide character (such as a space), I could then continue typing wide characters.

After further experimentation, I have found the following behaviors:

  • Open a new document, you can immediately type wide characters
  • Immediately after hitting <Backspace> or <Delete>, you cannot
  • When you hit <Return> and are starting a new line, you cannot
    • Even if you were just typing them on the previous line
    • Even if Padre auto-indented the line for you by any amount

I was playing around with this a bit with Hungarian and Hebrew which is even worse as it is written right-to-left.
With Hungarian I sometimes see this behavior (e.g. after pressing Del I can type ú bout not ő )

I could not reproduce the same bug in the wxRichTextCtrl example of wxDemo. Could you please try that and let us know if you can reproduce it there ?

err, that was misleading as STC (Scintilla) - the one we use is called Wx::StyledTextCtrl? and the demo is using something else that is called wxRichTextCtrl so that's irrelevant.

Refining my findings:

After pressing Del I cannot type ő or ű but I can type any other Hungarian vowel.
If I press any key (including the Shift or Ctrl) after that the above two characters
can be also typed.

running on Ubuntu 9.04

$ perl -MWx -e'printf(qq(Wx Version=($Wx::VERSION) %s unicode=(%s)\n), Wx::wxVERSION_STRING(), Wx::wxUNICODE())'
Wx Version=(0.91) wxWidgets 2.8.9 unicode=(1)
