Change keyboard input method to unicode?

I am going to create an application called 'khmer keyboard input method' the khmer just come in unicode standard (Range: 1780–17FF).

reference http://www.unicode.org/charts/PDF/U1780.pdf

this application it will allow cambodian to switch from English to Khmer by press the definded shortcut key (F10 for example). the application I will improve GUI.

for example

if keypress is 'k':
    return unicode(u'\u1780')#KHMER LETTER KA
if keypress is shift+k or is 'K':
   return unicode(u'\u1782')#KHMER LETTER KO

 #.....................

 if keypress is 'F10':
      switch_to_english_keyboard

Hooking keys and sendkeys is different way for Windows and Linux, so you have to do it seperately. In Windows, you can use combination of PyHook and SendKeys

For Linux,I have done to this

Anybody here Know to do this in python(tips,sample,..) (Just for WINDOWS )? it will be great if there are a simple code or any open source that make it more easy.

There is no single way. Each IME has its own way of picking a different engine/method.
