If you have unicode strings, you may need to do even more because
there are often multiple ways of representing the same glyph. I made a
little demo at http://rpubs.com/hadley/unicode-normalisation, since

R does no interpretation of strings when doing comparisons so you do
have do your own canonicalization. That may involve removing
trailing, leading, or all white space or punctuation, converting to
lower or upper case, mapping nicknames to official names, trimming to

How would I get a list of only the unique values of these two
character vectors. I would like the output a b c d e f there is no
reason to have these in order. I am looking at to character vectors
