WARNING - Word boundary \b does NOT work for non-latin alphabets
The word boundary test \b checks that there should be \w on the one side from the position
and "not \w" – on the other side.
But \w means a latin letter a-z (or a digit or an underscore), so the test does NOT work for other characters,
e.g. cyrillic letters or hieroglyphs.
