track names and unicode using MP4Box and mkvmerge

[stax76]

Is it possible to have track names containg unicode strings like 'русский'. I've tried ':name=русский' with MP4Box and '--track-name "0:русский"' with mkvmerge, using Haali's splitter and Zoom Player I see only '?????????' instead of 'русский'.

mp4box will not correct the language code you used in your cmdl to utf-8, so you will get in the mp4 what you used. the specs require it to be in utf-8 tough

I'm totally cluless about all this. Is command lines and UTF-8 even possible? Windows has ANSII and UTF-16 functions I think, I just found a good link, I'll likely have a better idea after reading it.

via command prompt its possible to use utf-8 but not via batch afaik
we discussed this already in the context of tagging via cmdl. kurtnoise found a way to set a correct utf-8 tag/trackname via his gui
apart from that i think mp4box also allows to use external "trackname" files (in utf-8) iirc

Do you mean that thread were you wrote to enter chcp 65001 in the console? I've tried that with the string posted above without success. I had of course also tried Yamp which did not work either.

yep thats what i meant

That don't work with unicode strings like 'русский'.

what do you mean by "which did not work" ? During the playback or for parsing cmdl ? coz it works fine here...

I mean Haali + MPC does not display it using MP4 but it works using MKV. How do you see that it works?

It's because you didn't use MPC mp4 splitter...;)

By enabling MPC mp4 splitter, you can see your trackname in the properties :

Anyway, if you prefer to use Haali's splitter, you have the right trackname in the systray icon (but not in the properties) :

Hope it helps...

I did no encoding transformation. It seems that what I have to do is pretty much a hack as UTF-8 is multi byte encoding which has to be passed through UTF-16 API's which is two byte. It is hard to understand why UTF-8 encoding is used while Win32 uses UTF-16. Either I miss something or it seems not possible to create such a file using the shell and it's a pain and a hack doing in from code. In the command line preview of our applications some weird strings appears because of the needed encoding transformation.

When I paste my string in Yamb in the import settings it does not display the string, though it works perfectly. Does it display on your system? What font are you using?

i am not sure but it might be utf-16 is also allowed, check the specs

Both should not be possible.

Useless because strings are converted in UTF8 for import settings. If you want to see a string converted, check the cmdl preview...You can copy & paste what you see in your cmd.exe, it works.


btw, I don't understand your problem with UTF8 vs UTF16.

[bond]

Both should not be possible.i dont understand what you mean by that!?

anyways i checked the specs myself and there it says about the trackname field:
name is a null-terminated string in UTF-8 characters which gives a human-readable name for the track typeso utf-16 is not an option, only utf-8

Null-terminated ? In Matroska no string needs to be null-terminated.
