When converting old notes from syntax orgto, mmdI used the Clean Text application to remove extra lines and non-Unicode characters and convert to safe lines. When pasting text back into Sublime Text 2, I noticed a few odd characters. I do not care why they are there, I just wanted to know what kind of characters they are, and if they are searchable using regular expressions?

They are control characters , they do not have a printed representation. I do not know how they ended up in your file.
