dear everyone,
I have added a couple of commands to the Invisibles.tmbundle. One turns the 'smart' quotes that look awful in HTML, etc., into plain quotes. The other deletes all 'non-ASCII' characters.
Now your favorite non-English language might have some characters that Invisibles thinks are gremlins and which get colored red and deleted in the Zap. You can change the pattern yourself to better suit your needs, in the Invisibles.plist and the Zap Command. You may want to refer to an ASCII chart (just google it).
You can get this last bundle from http://math.sfsu.edu/hsu/textmate/ but most of the fun stuff is happening at the TextMate SVN site. http://anon:anon@macromates.com/svn/Bundles/trunk
Perhaps soon there will be a cron script that zips up the latest Bundles automatically...
best, Eric
