Errors not noted with different kinds of apostrophes

[groenroos]

There are a few separate commonly used apostrophe characters (', ’, ‘). However, the word list only uses ', which means spelling mistakes using other types of apostrophes will not return any results. The package should perhaps include this easement, and accept any of these apostrophe characters as the same ' used in the dictionary.

A similar issue may also exist for the various kinds of dashes and hyphens.
