ParserInput

ParserInput reading directly off a byte array. This avoids a separate decoding step but assumes that each byte represents exactly one character, which is encoded by ISO-8859-1! You can therefore use this ParserInput type only if you know that all input will be ISO-8859-1-encoded, or only contains 7-bit ASCII characters (which is a subset of ISO-8859-1)!

Note that this ParserInput type will NOT work with general UTF-8-encoded input as this can contain character representations spanning multiple bytes. However, if you know that your input will only ever contain 7-bit ASCII characters (0x00-0x7F) then UTF-8 is fine, since the first 127 UTF-8 characters are encoded with only one byte that is identical to 7-bit ASCII and ISO-8859-1.
