Why's that silly? The uppercase form of ß is SS. PHP isn't case-insensitive

at the moment, merely case-insensitive for ASCII only.

This alters the issue somewhat - it opens up the unicode can of worms
and it's almost completely unresolvable without changing the rules for
identifiers fundamentally.


Certainly some people will be unaware of a number of ramifications of sorting out one problem ... using Unicode generally ... and things like 'case sensitivity'. Case conversion of UTF8 strings may also change the number of bytes used in addition to the secondary problem of changing the number of 'characters' but that is a more general problem 'upgrading' to Unicode multybyte characters which prevent the general use of the simple byte comparison functions.
