It's based on the charset.
For obvious reasons, UTF-8 is excluded here. What would be necessary for
a plugin like this to work with UTF-8 is snooping the content. I once
had a quick look at it -- seems rather straight forward to solve for
Cyrillic, but was much harder e.g. for Chinese chars.

char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4";
main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1:
(c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}
