I've not had the chance to use this module (yet). But the documentation is a sheer delight to read, probably because I've been reading too much Ted Dziuba (see bit.ly/e4GAgh). More modules should be this powerfully simple.
Just perfect - Does one job and does it well. It took me about thirty minutes after receiving a problem report from a customer to find this package, install it, integrate it into our code and get it out into production.
Nice module. Simple interface but no updates for 7+ years and the version number is 0.04 and has this rather long TODO list. Seems to work ok with latin languages but not so sure about the performance/correctness with chinese, japanese or arabic. There seems to be converters for ZH/JP at least but this wheel is not yet re-invented as a whole as it seems :)
