Update of bug #55452 (project octave):

                  Status:          Ready For Test => In Progress            


Follow-up Comment #14:

I forgot that "textscan" has been worked on already (see comment #5).

Could you please try with the attached patch. It should fix the weird error
message and add preliminary support for "fgetl".

I was wondering about format strings like "äöü %s %.3f", i.e. format
strings that don't consist exclusively of format specifiers. We probably would
have to somehow detect which parts of the format string are specifiers and
convert only the remaining parts before we pass the string to the C
Unless, "%s" (or any other format specifier) encodes to the same byte sequence
in these encodings as it would in ASCII (like it does for UTF-8).
Supporting UTF-16 or UTF-32 probably just gets weird. Maybe we should defer
those to later.

(file #46477)
