For readability, I strongly recommend 0x0020 over ' ' in this context.

What is the behavioural difference between <U+2060, U+0020, U+2060> and

However, if you reread the section, you will see that the sequence
they have in mind is <U+2060, U+2009, U+2060>.

No, this doesn't work. While the primary purpose of U+2060 is to
prevent line breaks, it is also used to overrule word boundary
detectors in scriptio continua. (It works quite well for
spell-checking Thai in LibreOffice). It's name implies to me that it is
intended to prevent a word boundary being deduced, through the strong
correlation between word boundaries and line break opportunities.

There doesn't seem to be a code for 'zero-width word boundary at which
lines should not normally be broken'.
