POSIX says [:alpha:] must be supported: 4.1 awk - Pattern scanning and processing language ... 4.1.7.4 Regular Expressions The awk utility shall make use of ERE notation (see 2.8.4) except that it shall allow the use of C-language conventions... 2.8.4.2 ERE Bracket Expression The rules for ERE Bracket Expressions are the same as for RE Bracket Expressions; see 2.8.3.2. 2.8.3.2 RE Bracket Expression ... (6) A character class expression shall represent the set of characters belonging to a character class, as defined in the LC_CTYPE category in the current locale. ... Strictly Conforming POSIX.2 Applications shall only use the following character class expressions, which shall be supported on all conforming implementations: [:alpha:] [:cntrl:] [:lower:] [:space:] [:alnum:] [:digit:] [:print:] [:upper:] [:blank:] [:graph:] [:punct:] [:xdigit:] ...
