/* The locale names as used by Windows are in the form
* "German_Germany.1252" or "German_Austria.1252" with
* alternate names similar to Unix, e.g. "de-DE". However
* that is the theory. On current Windows and Mingw the
* alternate names do not work. We would need a table to map
* them from the short names as provided by gpgrt to the long
* names and append some code page. For now we use "" and
* take the locale from the user's system settings. Thus the
* standard Unix envvars don't work for time and may mismatch
* with the string translations. The new UCRT available since
* 2018 has a lot of additional support but that will for sure
* break other things. We should move to ISO strings to get
* rid of such problems. */
