Detailed Description

Iterate chars and ANSI SGR in a multi-byte character string.

The iterator offers (pos, size) of the current wchar within the original text_r. Also the number of columns the current wchar occupies on the screen.

Note
: The iterator contents fakes all WS to either '
' or ' '.
: isCH includes SGR sequences
