Sending a "char" to macros like isupper(), isalpha() where the character is > 127 will cause serios problems on some machines/OS. The reason is that - 'char' may be unsigned, i.e. the Swedish char '�' will + 'char' may be unsigned, i.e. the Swedish char 'ä' will as a number be negativ. The implementation of isupper() and others will on some machines use an array that is indexed with the incoming - character code. The Swedish '�' will then create an access + character code. The Swedish 'ä' will then create an access on memory outside the array! This may give a random value as a result or a segmentation |
