// According to

//
// A uniform type identifier is a Unicode string that usually contains characters
// in the ASCII character set. However, only a subset of the ASCII characters are
// permitted. You may use the Roman alphabet in upper and lower case (A–Z, a–z),
// the digits 0 through 9, the dot (“.”), and the hyphen (“-”). This restriction
// is based on DNS name restrictions, set forth in RFC 1035.
//
// Uniform type identifiers may also contain any of the Unicode characters greater
// than U+007F.
//
// Note: the actual implementation of xcode does not allow some unicode characters
// greater than U+007f. In this implementation, we just replace everything non
// alphanumeric with "-" like the rfc1034identifier macro.
