The standard regexp library does not support unicode and I was not 
planning to write my own regexp compiler any time soon.

As a matter of fact, I haven't looked at TRE before. I'm quite 
interested though, since it is backwards compatible with POSIX and seems 
to be available in most systems. I'll give it a closer look, also in 
terms of compatibility with the latest draft of the Sieve regex 
extension specification.
