Our CMS does not support Unicode text thus when we need to search-replace for characters like the ™ and © symbols. This takes a fair amount of time and is easy to miss so I wrote a script in AutoHotKey to automatically handle the Unicode character encoding.
Now I can highlight the word and click a button and Whamo! Instant replacement with HTML equivalents! No more trying to scan text and find illegal characters.
Here is the AutoHotKey code I use. My code first grabs the highlighted text and copies it to the clipboard, where it manipulates it, then sends it back to the active program I was working in. No more need for Unicode character encoding!
