This code
print mb_substr('éxxx', 0, 1);
prints an empty space :(
It is supposed to print the first character, é. This seems to work however:
print mb_substr('éxxx', 0, 2);
But it's not right, because (0, 2) means 2 characters...

Try passing the encoding parameter to mb_substr, as such:
print mb_substr('éxxx', 0, 1, 'utf-8');
The encoding is never detected automatically.

The encoding is never detected automatically, it just always defaults to something.

Could it be a better idea if you use
mb_detect_encoding to actually try to detect the encoding?deceze
@AlvinWong No. Know what encoding you're working with, there's no other way.

@Alvin Wong, that would be more correct, yes, but I could also say that using anything but utf-8 can be considered adventurous and marginal :)

OK, then how about
mb_internal_encoding instead of passing "utf-8" to all mb_* functions? Just like Álvaro G. Vicario has pointed out |
In practice I've found that, in some systems, multi-byte functions default to ISO-8859-1 for internal encoding. That effectively ruins their ability to handle multi-byte text.
Setting a good default will probably fix this and some other issues:
mb_internal_encoding('UTF-8');
