Escape or replace invisible or ambiguous characters when formatting strings

See original GitHub issue

Invisible characters such as zero-width joiner and non-breaking space, as well as ambiguous characters like other kinds of spaces, combining characters et cetera should be escaped when strings are formatted. should be used where the behavior of the original character is preserved. This probably only applies to linebreaks.

If a simple escape sequence exist it should be used. Else characters should be escaped using the \u sequence.

When a string is formatted as a key it must not include linebreaks.
