Overrides org.jcodings.MultiByteEncoding.length.

Returns character length given character head returns 1 for singlebyte encodings or performs direct length table lookup for multibyte ones.
public int
length(byte[] bytes, int p, int e)

Implements abstract org.jcodings.Encoding.length.

Returns character length given stream, character position and stream end returns 1 for singlebyte encodings or performs sanity validations for multibyte ones and returns the character length, missing characters in the stream otherwise
