    Add string literals from proper character groups

    Add string literals from proper character groups
    
    Escape prefixes were included in the strings being passed to the
    character composition functions, resulting in incorrect characters
    being generated (in the case of control characters) or exceptions
    being thrown (in octal and hex literals, in combination with the
    OCaml-specific prefixes).
