All Windows systems to my knowledge come with an application called Character Map

You can see all the characters supported by a font in it and cut/paste from it... For instance when I am making a set of names for my characters... say Sychosys.. I will generally have 2-3 characters with some sort of accent or grave or what not over/around them just to ensure I can use the names and then vary them by one of the characters.. For example I make the string Sýchòóôõösÿs in Character map, activate the main WoW screen and paste that in so each person has that name, then just delete all but one of the O's to get the name variance.

Dunno if this helps, but it made things a bit easier for me.
