It 11encompasses features from different regular expression implementations 12that traditionally exist in different languages. 13 14Character encoding can be specified per regular expression object. 15 16Supported character encodings: 17 18 ASCII, UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE, 19 EUC-JP, EUC-TW, EUC-KR, EUC-CN, 20 Shift_JIS, Big5, GB18030, KOI8-R, CP1251, 21 ISO-8859-1,
