python - affichage unicode dans wxTextCtrl - Stack Overflow ~ Stackoverflow Blog

I am using python 2.7 for creating a text editor. I am able to create the corresponding Unicode Malayalam(Indian Language) characters but I am not aware how to display it

on text control. I need to work the text Control like a Malayalam Text Editor. The editor should support the space, newline ,

insert characters also..it should work like a note pad. I am pasting the code which I have. 1. engine.py is a mapping file which does all the mapping and at the back-end it will generate the Malayalam letters. All I

required is to get it displayed on screen correctly. the engine.py code and texteditor.py code are as below

The texteditor.py is the file which has to be executed. conv(self, event) is the function which performs the conversion to

Malayalam. The issues I am facing here are 1. when I press space after entering a word in the textCtrl The first english word will also displayed on screen along with the

corresponding malayalam word conversion in the screen. This should be corrected. 2. when I start to enter the second line onwards eventhough it displays letters of malayalam in the editor window when i

press space , the last letters of the previous word will also truncate. This should also be avoided. Please help me to correct

these two problems. I have pasted the full code here. Let me know where it goes wrong in the code . My final aim is to build

a texteditor for malayalam like the notepad. Kindly help me...
