Try:

    > =escape( "12345;:/<>%" )
    %1%2%3%4%5%;%:%/%<%>%	10

which is probably not what you wanted. So you need to put a few more 
escapes in there (at least before `%`, `.`, and `-`) ...

p.s.: Maybe we should have a string.escape() function in Lua's standard 
library (or at least an example in the ref manual ready for copy & 
paste) ...
