Add utf8 decoder taken from http://bjoern.hoehrmann.de/utf-8/decoder/dfa/ by Björn Höhrmann, under MIT license. Signed-off-by: Davide Bettio <davide@uninstall.it>
This change removes a shift operation and shorten the table. Signed-off-by: Davide Bettio <davide@uninstall.it>
There was some code duplicated for validating UTF-8 strings, that was even performing full decode. Use instead new `unicode_is_valid_utf8_buf` function that is also based on highly optimized code. Signed-off-by: Davide Bettio <davide@uninstall.it>
Use it as a drop-in replacement instead of bitstring_utf8_decode. This function is based on highly optimized UTF-8 decode found here: http://bjoern.hoehrmann.de/utf-8/decoder/dfa/ Signed-off-by: Davide Bettio <davide@uninstall.it>
