            Bug ID: 218600
           Summary: printf family returns number of bytes written, not
                    characters
           Product: Documentation
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: low
          Priority: P3
         Component: man-pages
          Assignee: documentation_man-pages@kernel-bugs.osdl.org
          Reporter: quirin.blaeser@freenet.de
        Regression: No

For comparison:
https://pubs.opengroup.org/onlinepubs/9699919799/

In an utf8 environment the number of bytes written may differ
from the number of characters.

Example:
fprintf( stdout, "%*s\n", fprintf( stdout, "öäüÖÄÜßµł€\n"), "^");

From https://man7.org/linux/man-pages/man3/dprintf.3.html:
"Upon successful return, these functions return the number of
 characters printed (excluding the null byte used to end output to
 strings)."

Greetings.
