[drupal-devel] PHP string functions overloading for multibyte support

[Piotr Szotkowski]

Hello.

Ok, I think I get it. The Drupal's *_utf8 functions use the "classic"
(non-multibyte) string manipulation functions as something that
manipulates on bytes, not characters, and *depend* on such behaviour,
right?

That seems to make sense. Do all of such Drupal wrapper functions
contain utf8 in their names? If not, is there some place that lists
all these functions, so I won't miss any?

If I come with a patch for this, should
I send it here or someplace else?
