ah, i'm not using unicode. my favorite editor (mcedit) is not good withunicode anyway and my locale is not utf. ;-)
That sucks! Now I had to do it myself. (I think you should upgrade to a decent editor on a decent OS and save me some unicode-work…;)
Implementing "tmpl‹a,b›" and "tmpl«str»" was tedious, but I believe √ and π can be done in a heartbeat.
