When I use Quick Look in the Finder on a text file, it'll inevitably render garbled because it treats it as MacRoman.

Can I do something to make it always use UTF-8, or, even better, be ever so slightly smart about encoding detection?

Maybe not all my text files are UTF-8. But I'm damn sure not a single one is MacRoman. Some people at Apple are still using OS 9 I guess.

It's a file attribute problem. See here, at the end, two links explaining it:

Basically, if you execute this: xattr -w 'UTF-8;134217984' yourfile.txt your file will appear correctly in QuickLook.

In my opinion it has to do more with the editor and the way it saves the file than with QuickLook.

In my opinion, the OS defaulting to MacRoman while the world has moved on is asinine. – kch Aug 3 '10 at 11:49
I guess now I need a way to run that for every text file I create. fsevents and Folder Actions come to mind. Would be nice if TextMate had post-save hooks too. – kch Aug 3 '10 at 11:52
Why don't you just save it as UTF-8 in TextMate? – mipadi Aug 3 '10 at 14:20
I do, that's indeed the problem. QuickLook thinks it's MacRoman anyway. Hence the garbling. – kch Aug 3 '10 at 15:01

I wrote a little script that taps fsevents and sets the xattr when a file is saved within my home.

I also reveal the file's extension, which is unrelated to this question.

Check out the script here:

The script must be constantly running, so a launchd job file would be most welcome.

Also, see my comment about using ~/.CFUserTextEncoding here.

Speaking of launchd, WatchPaths and QueueDirectories may do the job without my needing to tap fsevents myself. – kch Aug 3 '10 at 14:37
