<text>Four-byte ΓÇ£OSTypeΓÇ¥ codes are used heavily through the Macintosh system. Usually they consist of four printable characters, but this is not guaranteed. For this reason these externals support OSType values in two forms: either as a string of up to four literal characters (blank-padded at the end if fewer than four), or as a string of exactly eight hexadecimal digits. Values may be returned in either form, as four literal characters where possible, otherwise as eight hex digits.</text>
