Nice thread!
The more work done in C the faster it will be. So even though there is the overhead of compiling the regex expression, it frequently turns out to be faster. This is way I always use regex for tokenizers when parsing complex data (I did this for a Creole Wiki markup interpreter). Note that you can also convert the string to something like UCS-2BE using iconv and then each character will occupy exactly 2 bytes in the resulting string allowing you to iterate over it in the mostly convential way. This might turn out to be faster but I'm not sure.
