Description

The portuguese DVB-T broadcasts include special characters in the EPG that tvheadend doesn't handle properly. For example today there is a show that shows up as "Rex, O Cªo PolŦcia T12 - Ep. 2" instead of "Rex, O Cão Polícia T12 - Ep. 2". The program descriptions also have the same problems.

I'm running tvheadend 3.4.27~gfbda802~precise from apt.tvheadend.org/stable on Ubuntu 12.04.

The same happens in DVB-C. The Local Provider (net serviços) has the same problem. Not only in EPG, but in channel names too.

I just used tv_grab_dvb1 to test this. The solution was in a comment in dvb_text_iconv.c:

/* The spec says ISO-6937, but many stations get it wrong and use ISO-8859-1. */

Changing the next line to

char *iso6937_encoding = "ISO-8859-1";

and recompiling fixes the issue, so the solution for this feed would be to have an option in tvheadend to interpret the EPG as a different encoding.

I have a ugly workaround that "worked for me" until a month ago when the broadcast provider I use messed all up again.

Grab the git version, and change the following in src/dvb/dvb_support.c at line 269:

ic = convert_iso6937;

to

ic = convert_iso_8859[1];

As anyone figured out a "working" workaround for this? Or (hopefully) will we have to wait until the next release?

I had the same problem on my tv and the workaround was to set the country to spain and re-tune the channels. I don't know if there is an easy way of applying the same configuration to tvheadend.

Thank you.

You can already manually override the character encoding used on muxes and services.

Where is that? I can't seem to find it in the interface. I'm running 3.4.27~gfbda802~precise

Pedro, I think the option Adam means is under:
Configuration>DVB Inputs>TV Adapters>DVB charset (I'm running 3.4).

However I've changed mine from auto to ISO8859-1 but didn't see no effect. Should I restart the service?
The correct charset was ISO8859-1 or did I got it wrong?

An update. I've forced the refresh of the epg guide, but strangely only some of the special characters were fixed, the others remain the same.

On my setup the setting is in Configuration>DVB Inputs>TV Adapters>DibCom 7000PC>Services and is a per-channel setting. After setting it on all the channels and restarting tvheadend the program guide seems correct. It would be nice if there was a setting at the Multiplex level so that if new channels pop up they get the correct setting without intervention.

nf gb, if not all the characters are correct you probably need some other iso8859-X. Check this table to see if there's one that's related to where you're from:

Pedro,

On mine is also on channel level (maybe I didn't express myself very well - in portuguese would be a lot easier ;) )
I'm also tuning Portuguese DVB-T (TDT). It is ok now. I've forced an additional refresh on the epg. The strange thing is that on the first refresh it didn't update all the entries.
