alexey.lysiuk 574e079f17 - use own implementation of iswalpha() function
Character classification is no longer affected by quirks of standard library implementation
Lookup table for own function was generated with Python thanks to Unicode Database module from its standard library
Explicitly set locale for POSIX targets was reverted to C
