Basically all that is required is to set the lexer to STC_LEX_CONTAINER, 
and then respond to the EVT_STC_STYLENEEDED event where you need to set 
the styling info up to the position specified in the event object.  I 
don't have any good examples of this, but be sure to read the Scintialla 
docs to get a better idea of how the underlying code works.  Translating 
that to wxSTC and Python shouldn't be too hard.

The STC stores the document data internally as utf-8 so what you are 
seeing as column offsets is actually related to character positions in 
this buffer where some characters can occupy more than one byte.
