I don't like the idea of having a "u" prefix for Unicode strings. It may improve performance, and give you some level of fine grain control, but... - It breaks your "keep php simple" policy by introducing a lot of new functions (ugly). - I (plus a lot of others) have an existing php5 application which I wish to eventually use with Unicode, and like others, I don't want to spend time refactoring. - It will also introduce bugs when programmers accidentally forget to add the "u" prefix when working with unicode. If you always want to produce Unicode, I think its best to always use a cast or a conversion function. Eg $str = (unicode)(strtoupper($str)); Or $str = unicode_val(strtoupper($str));

Good idea and it will totally work, except that it won't. strtoupper() operates in different ways according to the type of the string that it gets. -Andrei
