I answered this yesterday, but I don't see my answer here...

Anyway, my answer was: no, a lexer cannot change the text in the buffer, 
or at least it should not do it.
And it sets style ids, but it doesn't choose how a style is rendered. 
That's the task of Scintilla, following the settings set by its client.

It is about a source code editor, not a rich text editor: if, for 
example, you do a markup lexer, you can be tempted to hide the 
characters of the markup and show the appropriate rendering, but then it 
would be hard to manually remove or change the markup. It would be the 
task of the client to offer commands to do so... But, again, that's the 
wrong component to use for this task.
