I do not know whether Apple Mail does the encoding the way Spotlight does,
but here it is:
<quote from Amit Singh's "Mac OS X Internals">
The four-character file type is converted to a four-byte (32-bit) integer,
each of whose bytes is the ASCII value of the corresponding file type
character. The ASCII values of "t", "b", "x", and "i" are 0x74, 0x62, 0x78,
and 0x69, respectively. Therefore, the file type to use while searching with
Spotlight is 0x74627869.
