Enhancement: Set charset for all files to UTF-8

[localheinz]

This pull request

• sets the charset for all files to UTF-8

Follows #554.

💁‍♂️ I would not mind pulling up more attributes!

Still using mixed indentation in PHP files, but could be easily fixed after merging #559 and enabling the indentation_type fixer.

Hmm, are we sure that all files are UTF-8 encoded? What about binary files (e.g. some images)?

PS: well, binary files shouldn't be an issue.

I am not sure.

Looks like most, if not all, files are already UTF-8 encoded, and any accidential changes should be caught when reviewing the commit, so let's merge this.

Thank you for the RP!
