[TxMt] Problems handling Windows-encoded files

When I try to open files that have extended characters (e.g. curly apostrophe) and are saved with "Western - Windows" encoding, TextMate 2 gives an "Unknown Encoding" error with a hex dump of the file and asks for the encoding. If I choose "Western - Windows", TextMate opens the file successfully. (The default encoding is set to the default, "Unicode - UTF-8".) Also, if I have a project containing these files, Find In Project fails because TextMate sees them as binary files.

Is there any way to have TextMate autodetect the encoding so that opening and searching files works as expected? Thanks,
