Minor fix of Danish characters in Teletext (1 Viewer)

[johnlc]

I have noticed that a few danish characters is wrong in the translation tables. Here is example from TeletextPageRenderer.cs in TVClient Plugin
m_charTableC
{ 'Æ', 'Ø', 'Å', 'Ü', '_', 'é' },
Notice Æ Ø Å in group txtLanguage=11

m_charTableD
{ 'æ', 'ø', 'å', 'ü' }
Notice æ ø å in group txtLanguage=11.

This fix I have tried and it works in TVClient Plugin (may be in other places too)

The is not a major thing, but maybe it could be fixed at some point

Could u supply me with a diff/patch file of the changes made ?

this is for teletext TV only ?
Or teletext based subtitles also ?

Yes, I think the issue is both places, but I have been strugling with Oracle database since friday evening - so give me a few days

Here is the the places I think it should be changed. It wouldn't accept .diff, so they are called .txt

Thx.
Its in SVN.

Hello!

As a coincidence I tried the teletext with the latest tvplugin. And now I also have the danish characters, at least theese two are now wrong:
Æ/æ instead of Ä/ä
and Ø/ø instead of Ö/ö
It could be more that is wrong but theese two I saw instantly. Could you try to find a fix that would satisfy us all? I know this behavior will not be very welcome in at least Finland and Sweden.

No I can believe that.
But it should only affect what is called txtLanguage=11 in the code. I will have a look at it tonight.

Well I may have opened the box of Pandora here, because this wont be easy. Somehow it must be possible to detect, DK,S,N,SF (and Iceland?) further The Faroes and Greenland may also apply to the same language code=2

As you can see below my test shows that DK&S both use byte 115 and N uses 100 (but is this persistent?)
But here are my findings, and a clip from something about Teletext character sets I found.
Maybe Gibman needs to rollback the changes for now - until a better solution comes around.
I don't want to create to many complaints for the team as they are doing an excellent job - and don't need this disturbance right now- I can compile my own for the time being ( just as johnzered said about Ø/ø, I can say that the characters Ö/ö are not welcome on my screen )

Documentation found on Internet:

The remaining flags are called ``Suppress header'', ``Update'', ``Interrupted Sequence'', ``Inhibit Display'' and ``Magazine Serial''.
There are also three control bits which can be used to select one of 8 national character sets.
All 8 sets share the same basic 83 characters but modify the remaining 13 characters
(23=# 24=$ 40=@ 5B=[ 5C=\ 5D=] 5E=^ 5F=_ 60=` 7B={ 7C=| 7D=} 7E=~).
Unfortunately, there are more National options defined than there are bits to represent them,
so the right decoders must be used in the right region:

Control National
Bits Character Option
000 English or Polish
001 German
010 Swedish
011 Italian
100 French
101 Spanish or Serbo-croat
110 Turkish or Czechoslovakia
111 Rumanian

PS
The attached tvplugin.dll is if someone wants to see the codes for their country,put it in mediaportal\plugins\windows
Remember to keep your old copy!!
It only works for the TVclient plugin, I guess.
You can see the lines in Mediaportal.log file.

If the same codes are used for different languages then we might need to use a user setting to get the correct characters. Right now we are choosing a language in the configuration of mediaportal. Why not use that setting to get the right characters?

dhasselqvist,
Any chance that you can try this TVplugin.dll (for the latest SVN) - here I have tried to get this language.
It should be put in \Mediaportal\plugins\windows - but remember to keep your old TVplugin.dll, so that you can replace it again.

If you are satisfied, then which countries are affected?
Denmark,Norway use Æ,Ø
Sweden, Finland uses Ä,Ö
But Iceland, Faroe Islands - I simply don't know what they use, but everybody seemed happy until I stuck my nose in so I guess it's just a DK thing and N.
