Reply To: strategy for replacing two text characters with one glyph

You're using Applescript, so you're on a Mac. In which case you can hunt down the character(s) you want from the Character Viewer in your menubar (and if it's not there, you can turn it on in System Preferences under Language & Text > Input Sources). You can type the name or unicode ID into the search box and then choose the character and click on it to make it insert at your cursor in your search box or your script editor. Then just use a Text or Grep search as normal.
