True. Missed that.  I quickly looked, and noticed two things:

- Does it (still) work, since it seems to include an includefile with
  functions as implementation that return a "char"?
- The tformatsettings is still ansistring. However if the default locale is
   UTF-8 this might translate to unicode?
