UPC is a provider for middle european countries (Czechia, Hungary and Poland). They use iso6937-2 for encoding their EPG data so this looks quite strange in the vdr. The applied patch does a "remapping" to iso8859-2 so that characters are displayed correct. (Currently only tested with Czech and Hungarian, but should also work for Polish)
While testing this with the help of an hungarian user, i also found out that the the codepage for Hungary must be 8859-2, not -1.
The patch is work by Helmut Auer.
