Comment:

 I'm unable to reproduce most of the issues described in this ticket.

 - A category created as "Foo’Bar" is properly retrieved using `get_cat_ID(
 "Foo’Bar" )`
 - A category created as "Foo'Bar" is properly retrieved using `get_cat_ID(
 "Foo'Bar" )`
 - Both categories can be edited at wp-admin/term.php without changing the
 apostrophe formatting
 - I can confirm that `Foo'Bar` is showing as `Foo’Bar` on edit-tags.php,
 but this is just a formatting issue, and doesn't appear to affect querying
 by `get_cat_ID()`

 One thing I can confirm is that `single_cat_title()` is being run through
 `wptexturize()` (ie, the return characters are HTML-encoded). But
 `single_cat_title()` is meant for display, not for fetching data for the
 purposes of querying. If tutorials around the web say otherwise, then the
 tutorials are incorrect :) `get_queried_object()` is the best way to
 identify the category on a term archive.
