Please note that dc.drawText() does not do any formatting, it just draws
the visible characters and draws "replacement" characters for the formatting
characters like \n and \t.
If you want interpretation of the formatting, just place a text widget and
it will do a lot of formatting for you; alternatively you can write a loop;
here is what FXLabel uses:
while(end<text.length() && text[end]!='\n') end++;
I know you're working in Ruby, and this is C++. But I hope you get the
idea:- hunt for the \n, then draw up to that, move to the next line and
hunt for the next \n. Repeat until the whole string is done....
P.S. As for utf-8, this capability will be in FOX in the 1.6 version;
the plan is to have unicode drawing support for all widgets, and have
some stuff in place for localization.
