We should let external collator to handle all these fancy features. People can always normalize/canonicalize/do-whatever-you-want and send the result text/binary to regex. All the features we argue about here can be easily done by a customized collator. Do NOT expect the Perl regex be a linguist that can understand every language in the world and be able to match my name in English and Chinese :-) (Of course, that will be a useful feature for me.) Please note regex is O(n) at best, adding an external collator will make is O(2n). Put fancy unicode feature into regex will not make it any faster. My recommendation is to keep regex locale independent. And have some API for handling locale specific features, though I am not sure what is the best way to do this. HongThread Previous | Thread Next
