I demand that Thiemo Gehrke may or may not have written...
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)
Hmm. I recall seeing similar encoding being used by the BBC, though I don't see any examples of it ATM.
Obviously, the output encoding should be ISO8859-1, not -2...
