Did you know that Unicode includes a thumbs-up sign? To find it, select "Conversions and Tables", and in that list, pick "Unicode Data". Then type "thumb" into the on-screen search box. You can also list all of the Unicode character in the same set. Thumb, for example, is in Miscellaneous Symbols and Pictographs. Just enter that (or jut Pictographs!) into the search box.
