The way TM presently does it is by:
1) check if TM is set as the handler for this file type (in
Finder), if so, search it
2) check if the extension is known as a binary or text extension --
all extensions declared in TM’s Info.plist are known text extensions,
but you can right-click a file in the project drawer to toggle the
type for the clicked file’s extension
3) scan the first 8 KB of the file and check if it is a) valid
UTF-8 and b) contains no control characters (i.e. below 0x20) except
for tab and carriage return / line feed).
Files w/o extension will thus always pass/fall based on the third check.
When 2.0 is out, it should be easier to see which files TM chokes on
based on the new UI, at that time I’ll take input on improving the
heuristic, if there are still problems.
