Is CR considered whitespace? I always thought that was classed as a non-printable control character. But maybe I’m wrong?

Or are you talking about SP preceding CR and/or LF?



Line breaks are considered whitespace, hence CR is considered whitespace. It is also a control character. This is similar to TAB, or indeed LF.

See here for example: https://en.cppreference.com/w/c/string/byte/isspace

Or here for Unicode: https://en.wikipedia.org/wiki/Whitespace_character#Unicode


Ahh that makes sense then.

Thanks for the responses
