textutils: introduce and use fgetwc_or_err

A return value of WEOF of fgetwc() can either mean end-of-file or an
error in errno. The error was ignored and interpreted as end-of-file.
Introduce a new helper that aborts on error and use it in text-utils.

This replaces all calls to plain fgetwc().

Closes #2909
