>Description:
The man(1) utility allows some localization, by searching, for instance

  /usr/share/man/de_DE.ISO8859-1
  /usr/share/man/de.ISO8859-1
  /usr/share/man/en.ISO8859-1

Some languages however have several common encodings that are either upward
compatible or can be converted to a similar encoding with little (if any) loss
in information. For instance, German text can also losslessly(*) be represented
in ISO8859-2, ISO8859-15, several other ISO8859-* encodings and of course
UTF-8.

The man utility should be able to automatically convert between UTF-8 and the
installed ISO8859* representation, so that ports do not have to install the
manual pages for every common encoding.

(*) minor differences affect special characters such as the 1/4 1/2 3/4
ligatures or the EUR currency symbol (0xA9 in ISO8859-15).
