Improve checks compatibility with XML entities

[nijel]

Is your feature request related to a problem? Please describe.
The translated string can contain HTML or XML entities and the checks should deal with that gracefully.

• XML entity is likely to trigger punctuation spacing (for French and other languages using this)
• When it's in the end, it will trigger missing semicolon as well.

Describe the solution you'd like
The checks should deal with this automatically.

Describe alternatives you've considered
Manually ignoring such strings should not be needed.
