Clear and concise description of the problem

We had several issues where invalid characters were in the locale data for a particular locale.

E.g.

• fix(locale): replace Ð with Đ in hr and vi #1810
• fix(locale): mk (Macedonian) names should use cyrillic а #1557

Suggested solution

Verify the characters in the locale data using a test.

Alternative

Wait for community reports to fix the bad characters.

Additional context

Requires:

• [Feature Request] Add method to check if a text belongs to a given locale validatorjs/validator.js#2201

• I'm willing to create a PR.
