Your CMS is probably using "rich text" for its punctuation.
Verify that AA has been configured to use UTF-8 encoding. If you're using AEP Tags as your tag manager, then in your AA extension's "General" section, check that the Character Set has been preset to "UTF-8".
If that doesn't solve your problem, then you might need to ask your developers if they can set non-rich text in your data layer (if you're using one) or a JavaScript variable that you can use to set your AA Page Name.
