[sldev] UTF-8 open source fonts

[Lawson English]

I've been playing with llSetText and found that various characters that 
display in my Mac's character input pallet don't  display properly in 
llSetText OR in chat/IM.

A little more research revealed that different people with  clients on 
different OS's or even the same OS show different subsets of chars.

The problem appears to be that the included ASCII fonts are supplemented 
on-the-fly with whatever is available on the local OS, but whatever 
algorithm is being used to choose those supplemental characters doesn't 
always work.

Linden Labs should standardize on existing open source unicode fonts 
such as those found here:

Time would be better spent deciding which open source fonts should be 
distributed with SL, including the possibility of creating  
llSetFont(font) and llSetTextSize(size) for llSetText's use, and base 
any text-handling on THOSE fonts, rather than trying to perfect the code 
to grab whatever fonts are available on the OS. At the very least, 
having a standard distribution of multi-language fonts would make it 
easier to cobble together unicode support on-the-fly and make any future 
text-handling code easier to write and maintain since a known 
multi-language set of fonts will always be available in any SL distribution.
