The UTI Character Set 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.

Important: Any illegal character appearing in a UTI string—for example, underscore ("_"), colon (":"), or space (" ")—will cause the string to be rejected as an invalid UTI. At the API layer, no error is generated for invalid UTIs.
