Hello,
        It seems there is a bug in isspace() and other macros defined
in ctype.ha. isspace() returns a nonzero value for a lot of characters
that are not whitespaces. Changing all (int) in ctype.ha to 
(unsigned int) should fix the problem. Are the funtion version of 
these macros also affected?

Asking the bug reporter in private Email, I confirmed that it's not
a library bug, but incorrect usage of isspace() that caused the 
problem. In a nutshell:

	never call  the <ctype.h>  functions/macros with a
	char or signed char argument. It *must* be casted to
	unsigned char, instead.
