Re: [PHP-I18N] ctype_print returns false for British Pound symbol (and non-ASCII symbols)

In which character encoding is your '=C2=A3' represented? Remember that =
PHP =20
is ignorant about character encodings, a string is just a sequence of =20=

bytes, and it's up to the application developer to make all components =20=

agree on the character encoding used. If your '=C2=A3' happens to be =20
encoded in ISO 8859-1, then its byte representation is the same as =20
"\xA3", which is not a valid UTF-8 string.
