I'm reading a document in Adobe Reader 8.0. The document contains many mathematical symbols and Greek letters.
How can I do a search for a character like this? I've tried to copy the character from the document and paste in the search box, but the character is transformed by the copy-and-paste. (For example, I copy the Greek letter alpha and paste it into the search box, and it appears as a "registered" symbol (R inside a circle). I copy the "is an element of" symbol (looks a little like an epsilon) into the search box, and it turns into a "2".)
How can I just do a simple search for one of these characters?
