Hi,

thanks to kotext/kozoomhandler (that is thanks to David) kformula is now more 
friendly when it comes to zooming. These are the good news.

The bad part is that I didn't get the symbol font to work. There is a symbol 
font on every system. It comes with X11, it comes with ghostscript. It's the 
default font for symbols in kformula. (Yes, there are plans to support better 
fonts but that's another story.)

The difficulty is the non-standard encoding of this font. With Qt2 you could 
tell QFont to use "any charset". The glyph were available then by their 
native number (0-255). However it didn't work reliable in most cases and not 
at all with anti aliased fonts. I never tried this, though.

Qt3 doesn't support the "any charset" option anymore. And I cannot find a way 
to get to the glyph. Between 128 and 255 is nothing but garbage and the 
unicode values (see below) don't help either. Maybe I've missed something 
simple or my configuration is wrong. I've no idea. Does anyone know where to 
look for information or whom to ask? What's qt's idea about the symbol font?

thanks,
Uli

PS: To see the symbol font on your box try 
	xfd -fn "-*-symbol-*-*-*-*-12-*-*-*-*-*-*-*"

There also is a nice page that shows the unicode values to those symbol font 
glyph: http://www.dessci.com/support/tech/encodings/symbol.htm
