Function encoding_rs::mem::convert_utf16_to_utf8

pub fn convert_utf16_to_utf8(src: &[u16], dst: &mut [u8]) -> usize

Converts potentially-invalid UTF-16 to valid UTF-8 with errors replaced with the REPLACEMENT CHARACTER.

The length of the destination buffer must be at least the length of the source buffer times three.

Returns the number of bytes written.

Panics

Panics if the destination buffer is shorter than stated above.

Safety

If you want to convert into a &mut str, use convert_utf16_to_str() instead of using this function together with the unsafe method as_bytes_mut() on &mut str.
