Even if an encoding can express all accented letters in the given language,
we can't generally settle for it in DNF since sometimes we output special
characters like the registered trademark symbol (U+00AE) and surprisingly
many national non-unicode encodings, including e.g. ASCII and ISO-8859-2,
don't contain it.

Expansion can be left or right. This is what you want to use instead of
%*.*s, as it does the "right" thing with regard to different Unicode
character width.
prefix and suffix should be used for "invisible" bytes, like
highlighting.
Examples:
``"%-*.*s" % (10, 20, msg)`` becomes
``"%s" % (fill_exact_width(msg, 10, 20))``.
``"%20.10s" % (msg)`` becomes
``"%s" % (fill_exact_width(msg, 20, 10, left=False))``.
``"%s%.10s%s" % (pre, msg, suf)`` becomes
``"%s" % (fill_exact_width(msg, 0, 10, prefix=pre, suffix=suf))``.

depending on whether we have enough screen space to display the full
message or not. If a caller by mistake passes a long string as
msg_short and a short string as a msg_long this function recognizes
the mistake and swaps the arguments. This function is especially useful
in the i18n context when you cannot predict how long are the translated
messages.
Limitations:
1. If msg_short is longer than width you will still get an overflow.
This function does not abbreviate the string.
2. You are not obliged to provide an actually abbreviated string, it is
perfectly correct to pass the same string twice if you don't want
any abbreviation. However, if you provide two different strings but
having the same width this function is unable to recognize which one
is correct and you should assume that it is unpredictable which one
is returned.
Example:
``select_short_long (10, _("Repo"), _("Repository"))``
will return "Repository" in English but the results in other languages
may be different. N)rH )rK Z msg_shortZmsg_longZ width_shortZ
