How to change EPG "code page"

[hugo84]

Hi there.
I got a problem that started about a 1 week and half ago.
Suddly, I start seeing weird characters where it is supposed to be letters with accents, like á é õ.
I didn't change anything. This problem also affects media player MPC-HC (I contacted the dev years ago to add proper support to utf-8 and the characters appeared correct since then until... 1 1/2 weeks ago), it also affects a DVB-T box (it was working until 1 1/2 weeks ago, further investigation revealed if I changed EPG language from ALL to PT, things appear ok again).
The tvs connected to coax cable aren't affected by this problem because there is a setting that allows forcing the code page, but it is possible to replicate the problem of weird characters if I start from scratch and set country from Czesc (default from list) to UK. Name of the channels and description of the programs appear wrong.
I contacted my ISP about this issue and they appear to be clueless about this problem. I was contacted 2 days ago, I even sent them pictures.

I also have a Windows tool called DVBGuide and it is capable of extracting EPG listings from the coax streams like NEXTPVR does, but to a xml file.
When I open the xml file, it is possible to see utf-8 first line but when we check for where it is supposed to be letters with accents, we see other kind of characters.
I tried to investigate myself the problem but I got to the conclusion that my ISP or the EPG provider that injects data to the streams simply changed the codepage to something else than utf-8. They are probably trying to impose some compatible table for all devices.
No matter what conversions I make with the xml file, I can't get the letters with accents back.

Regarding Nextpvr, is there a way to force the codepage?
The following image shows an screenshot taken days ago. Below "TVI", it says "SIC Notícias" (whic is ok, but after a new channel cleanup/scan, it appears wrong...), where is is supposed to an ú it shows fused oe, the ó is a D with a dash... etc

If you are getting the data from DVB you will need to supply a one minute full mux capture of the problem frequency using sub's TS Capture utility. https://www.tscapture.com/ If you are using the XML file from EPG Collector zip and attach the file.

Let's try uploading the ts file...

No you need to use external store for large files. GoogleDrive, OneDrive, filetransfer.io, mega.nz etc.

The xmltv file is bad encoding for sure.

You put a password on it.

Try now. It was a sharing setting.

All good. Now sub will need to get it to see how NextPVR reads it.

Is the problem with the guide data or just the channel name? The "SIC Notícias" name is encoded two way 8859-1 and UTF-8 in that file. This channel name shouldn't get updated each EPG update, just on scan, but if the channel name is changing maybe that is because of using XMLTV as the source.

Basically, everything that has accents gets screwed.
I've no idea what they did, but channel names, programme names, and programme description get screwed.
I swear that it was working before. Maybe I can upload the programme database nextpvr has.
õ -> ó    ã -> ª    ç -> somesort of L    and so on,
