 On non-ASCII platforms, it returns TRUE iff this

 Also note, that because all ASCII characters are UTF-8 invariant (meaning they
 have the exact same representation (always a single byte) whether encoded in
 UTF-8 or not), C<isASCII> will give the correct results when called with any
 byte in any string encoded or not in UTF-8.  And similarly C<isASCII_utf8> and
 C<isASCII_utf8_safe> will work properly on any string encoded or not in UTF-8.

 the official Unicode property C<XID_Start>.  The difference is that this
 returns true only if the input character also matches L</isWORDCHAR>.
