Are you sure that it is the genuine apostrophe that you are looking for?  
See e.g. here:

> It depends on where you use this apostrophes. If you want to contribute for example to MusicBrainz, you should follow their rules: Use of basic ASCII punctuation characters such as ' and " is allowed, but typographically-correct punctuation (such as ’ for the English apostrophe) is preferred.
