Rust allows use of non-ASCII identifiers, which in Rust mangling scheme are encoded using Punycode. The encoding deviates from the standard by using an underscore as the separator between ASCII part and a base-36 encoding of non-ASCII characters (avoiding hypen-minus in the symbol name). Other than that, the encoding follows the standard, and the decoder implemented here in turn follows the one given in RFC 3492. To avoid an extra intermediate memory allocation while decoding Punycode, the interface of OutputStream is extended with an insert method.
