SIMD-accelerated UTF-16 length calculation from UTF-8 bytes.
Formula: utf16_len = byte_length - continuation_bytes + four_byte_leaders
Where:
- continuation bytes:
(byte & 0xC0) == 0x80 - four-byte leaders:
byte >= 0xF0
Functionsยง
- utf16_
len - Compute the number of UTF-16 code units for UTF-8 string.
