Previously this was restricted to the C standard subset
which restricted most values <= 0x9F, as that simplifies the C lexer.
However printf(1) doesn't need this restriction.
Note also the bash builtin printf already supports all values <= 0x9F.
Nice one.
BTW: do we also want to support the new modifier that bash has since version
5.2?
r. The `printf' builtin has a new format specifier: %Q. This acts like %q but
applies any specified precision to the original unquoted argument, then
quotes and outputs the result.
Have a nice day,
