Member Data Documentation

◆ char_index

template<class Mb_wc >
unsigned uca_scanner_any< Mb_wc >::char_index {0}
private

How many code points (possibly multibyte) we have scanned so far.

This includes code points with zero weight. Note that this is reset once we get to the end of the string and restart the scanning for the next weight level, but it is not reset when we reach the end of the last level.

◆ mb_wc

template<class Mb_wc >
const Mb_wc uca_scanner_any< Mb_wc >::mb_wc
