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.

http://graphemica.com/blocks/control-pictures 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.

It’d be great if we could show byte differences when characters look the same, like in this example: https://github.com/avajs/ava/issues/2451

ANSI codes should also be escaped.
