<i18n dev> RFR: 8356978: Convert unicode sequences in Java source code to UTF-8 [v2]

[Magnus Ihse Bursie]

> After we converted the source base to be fully UTF-8, we do not need to use unicode sequences (like \u0123) in string literals. Sometimes, that might still make sense, as for control characters, non-breaking space, etc. But for strings that is supposed to be a coherent text in a language that needs non-ASCII parts of Unicode, this is not so. Instead, having the sequences makes the text just harder to read and edit. We have already removed several such sequences before, but some remains.

Magnus Ihse Bursie has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains two commits:

 - Merge branch 'master' into utf8-sequences-in-src
 - 8356978: Convert unicode sequences in Java source code to UTF-8
