Chris.SE: You say you don't see these errors.
I would be grateful if you would check for this error:
Adele Roberts is on BBC Radio 1 weekdays at 04:00 and nearly always has "Adele's got you," at the start of the programme description.
If the Freeview EPG shows "Adeles got you," with no apostrophe then you are seeing these errors.
If the Freeview EPG shows "Adele's got you," with the apostrophe then I will accept that the errors may be Winter Hill only.

Freesat Diffs:
First with this amazing news - faster even than the clever lovinthetelly on digitalspy.
New, in the top secret Freesat test region:
811 IDEAL WORLD
814 CREATE&CRAFT
in glorious High Def!
The SD version are 812 Ideal World and 813 Create & Craft, so it's easy to compare the resolutions.
Take a sneak peek using postcode AM1.

Chris.SE: Sorry about the late reply.
Yes, these bad codes will be generally discarded by the receiver software leaving mostly grammatical errors due to the resultant missing quotes, dashes, hyphens and apostrophes.
As you know, the reason I am aware of the errors and no one else seems to be is I am fairly unique in having written EPG software for my own personal use.
In fact, I initially failed to spot the errors as I had included such a discard routine in my EPG program.
I became aware of them when they appeared in the output of the Huffman decoder, which I expect to be pristine UTF-8 and thus not needing to be processed.
The culprits are always much the same - never from ITV or Channel4 services.
The following is part of an automated dump from my program.
Note the Sony errors appear thrice because EPG for the three local multiplexes is sent from Winter Hill.
Invalid Character Codes in the EIT off North West multiplex BBC A. Date: 2019/09/18 01:20:19

A new stream has appeared sometime during the last two months in the Winter Hill BBC A and BBC B multiplexes with a Packet IDentifier (PID) value of 21 or hex 0x15.
From ETSI TS 101 191 V1.4.1 (2004-06):
"The present document specifies a mega-frame, including a Mega-frame Initialization Packet (MIP), which may be used for synchronization of Single Frequency Networks (SFN) as well as for the optional control of other important parameters in an SFN."
"The PID value for the Mega-frame initialization Packet (MIP) shall be 0 15."
A PID 21 stream has been present in the Winter Hill D3&4 multiplex for many years but is not present in the com7 and com8 multiplexes.

I had hoped digitalbitrate.com might show the new stream but apparently not.
0 - - DigitalBitRate
They have the Winter Hill BBC B on "738.166Mhz", which it isn't, it's on uhf 54- or 737.833MHz and they pay no respect to Hertz.
They have a section under the heading "This Mux has Ghost PIDs : total bitrate of these PIDs"
They inform us:
"These PIDs are not declared within the DVB tables. They are not usefull and are taking bandwith inside this Mux.
The PID list is available in PRODBR website, you can also contact us for more information."
It is a common error to refer to PIDs where streams are meant. PIDs don't have a Bitrate.
I couldn't find any PID list at the PRODBR website.
Finally, they show the Winter Hill BBC B Bitrate as 40.10 Mb/s. It isn't. It's now 40.209 Mbps but it used to be 40.215 Mbps so something has changed.
I would be interested in reports as to the presence or otherwise of a stream with PID 21 in the BBC A and BBC B transport streams from other regions.

Bad Character Update.
The BBC seems to have fixed its EPG text.
There are just two BBC events with errors left.
Curiously, it's the same expression in both events, but with different error bytes, specifically:
The low byte 0x10, substitute {-), of a Unicode hyphen 0x2010 in the first and the low byte 0x0B, substitute {), of a Unicode zero-width space 0x200B in the second.
As is most often the case, the EIT off BBC A has the error bytes and that off BBC B omits them. As usual, Freesat show what the text should be.

As for errors from other service providers, they continue much as before.

Tommy Mcaulay: The main audio for all four services is in AC3 format. The two that you have audio for have MPEG audio streams as well, for Audio Description, and that is what you'll be hearing. It appears your boxes don't support AC3 audio.

Two weeks on from the local multiplex frequency changes and the Winter Hill NIT is still showing all three on 754 MHz.
The responsibility presumably lies with Digital UK.
The DTT NIT seems to have been reduced to a carrier bag for LCNs and daft messages like this one: "Database right of Digital UK Ltd 2019".
They never bothered to include a decent T2-Delivery-System descriptor that showed the frequency of T2 multiplexes, thus eliminating the possibility of automatic tuning of the correct frequencies via the NIT.

Chris.SE: Responsibility for the Freeview EPG lies with Digital UK.
It has nothing to do with Arqiva as it's not a transmission fault.
The same errors are present in the com7 EIT, which has to be exactly the same everywhere for the SFN on UHF55 to work.
It seems likely that the same buggy software is being used by certain services to process their EPG data.
