metadata encoding detection not working

[jonath92]

When opening a file/stream with non UTF-8 characters (e.g. this stream: 'http://ic7.101.ru:8000/c1_2' which almost always has non UTF-8 characters in the metadata) non UTF-8 characters are not decoded. The relevant line in terminal output is something like this:

[display-tags]  icy-title: ��������� ����� & ����� - � �� ������� - 0:00

However when I open the same stream with Rhythmbox, it is shown correctly:

It also should be mentioned that this also occurs in other languages, e.g. for German streams the "Umlaute" (ä,ü.ö) are not shown correctly.

I first assumed that the problem occurs because mpv hasn't been built with uchardet as the docs mention:

uchardet will be used to guess the charset. (If mpv was not compiled with uchardet, then utf-8 is the effective default.)

but the behavior is still the same one a custom build with uchardet. AFAICS the problem either occurs because I haven't built it correctly or due to a bug. The building log included the following line why I assumed I haven't made a mistake:

Checking for uchardet support                                             : yes 

Important Information

• mpv version: problem occurs on 0.32.0 installed from the linux mint apt repo and 0.33.0-161-g83b4bc622a with a custom build
• Linux Distribution: Linux Mint 20.1 (which based on Ubuntu 20.04)

Reproduction steps

• Build mpv with Uchardet
• Open mpv with a file/stream with non UTF-8 characters (e.g. this stream: 'http://ic7.101.ru:8000/c1_2' which almost always has non UTF-8 characters in the metadata).

Expected behavior

• mpv is showing the metadata correctly

Actual behavior

• mpv is showing weird symbols in the metadata.

Sample files

Unfortunately I don't have a sample file but it is usually very good reproducible with the stream mentioned above. It also occurs with this stream: http://wdr-wdr2-rheinruhr.icecast.wdr.de/wdr/wdr2/rheinruhr/mp3/128/stream.mp3. However in this case it occurs much less often due the fact that many titles don't include non UTF-8 characters.

Any help is much appreciated.

this is remotely related to #8812(?)

there is still no solution to this issue?
mpv 0.33.0

File tags:
icy-title: Pianoboy - � ���� ���
A: 00:00:29 / 00:00:33 (88%) Cache: 3.8s/135KB

i tried setting --metadata-codepage=auto, tried changing different system encodings, have no affect, this issue is so annoying,
please help,

I haven't gotten around to reworking that PR yet, so there still is no solution to this issue as of now.
