a code point of a character
code, int
a character type to check against Oniguruma equivalent: is_code_ctype

length(byte[] bytes, int p, int end)

Overrides org.jcodings.SingleByteEncoding.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
public final byte[]
toLowerCaseTable()

Overrides org.jcodings.Encoding.toLowerCaseTable.

Returns lower case table if it's safe to use it directly, otherwise null Used for fast case insensitive matching for some singlebyte encodings
