Scripting tools to allow display of text on a prim: XyText 1.5 (aka XyText) , XyzzyText, XyyyyzText, XyText-UTF8, XyzzyText-UTF8, ZZText, VariText
XyzzyText doesn't work with European characters.. :( See also ZZText for a comprehensive International low-prim solution. XyText-UTF8 for the a full programmatic solution with standard xytext. I eventually found out that XyzzyText is really slower than XyText so I'm showing a comprehensive solution with xytext in previous link.
However here is a PhotoShop script and a variation on the main server you can use to adapt it to your needs if you are using UTF-8 fonts:
The theory is the following:
- prepare a 512x1024 texture with in the first part the standard Xyzzy chars, and in 2nd part customized characters (you can define up to 100 extra chars)
- modify the master and slave scripts to decode UTF-8 chars as explained below
- vertical parameters taken from XyzzyText standard text have been modified to allow the fact we have twice the characters in vertical size.
- typographical quality of the rendered characters is the same as the 512x512 texture version, since we are just expanding it, not compressing.
Very Important:
- The master script is very very tight on space, so if you really want to use this you have to cut much of it, in my real application I simply removed the extended verbs and the fading options, and rewrote the UTF-8 list using the x=(x=[])+x+newlist well known trick to save memory. If you don't do this you will likely get stack-heap collision.

Instructions on how to generate the texture are already published on Xyzzy main page, but just to be sure I repeat them here:
- openup photoshop
- click the vbs script in explorer and it will run over your photoshop
- add one temporary layer and fill it with black just to see your characters
- select one text layer and use "select similar layers"
- change your font, size etc from the text tool and look how they appear (NOTE: should be monospace font)
- merge all the selected layer into one single one
- go to channel tab in layers, and add one new (alpha channel) it will be black per default
- go to your font normal layer and select all
- go to your alpha channel and paste it down
- be sure to have the temporary black layer deselected and to select RGB layers so to see transparency in red
- save as tga 32 bit and upload it to SL.
