Frequently asked questions

Why does invisible whitespace cause bugs?

Because comparisons are exact. A trailing space means "London " never equals "London", a lookup fails, and nothing on screen explains why. It is one of the most common causes of a match that should work and does not.

What is a non-breaking space?

A space that prevents a line break, used in typography to keep "10 kg" together. It is a different character from an ordinary space, so text containing one fails an exact match against text that does not.
