Function Details | [hide private]

### b1_mapping(uc) | source code
Do RFC 3454 B.1 table mapping. Parameters: `uc` - Unicode character to map. Returns: u"" if there is `uc` code in the table, `None` otherwise.

### nfkc(data) | source code
Do NFKC normalization of Unicode data. Parameters: `data` - list of Unicode characters or Unicode string. Returns: normalized Unicode string.

### set_stringprep_cache_size(size) | source code
Modify stringprep cache size. Parameters: `size` - new cache size
