[Icecast] Character encodings in ICY metadata

[Greg Ogonowski]

UTF-8 handles ALL character sets. That’s the whole idea of Unicode.

We have encoder users all over the world using UTF-8.

Handles all Asian languages with no problem, including Burmese which is a more recent addition to the current Unicode version due to additional complications. Requires Operating Systems with the latest Unicode version.

Here is an HLS stream with metadata done right:

Note Extensible Metadata Fields have been set up with multiple languages, and they are all sent at once.

In order for this to work properly, the entire metadata path from start to finish is required to be UTF-8 Unicode. Any modern software is.

As long as "ALL" is defined as what English people need plus all emoji
in all skin colours but green.

There are still a lot characters not included even if the set they
contain to is in the list.


While UTF-8 is most likely the way you want to go, it is by no means
universal.

The truth is that ICY is just a broken protocol that does not give you
any way to define what charset you use. So you need to guess anyway.
Some software guesses by detecting special characters in the strings,
some by using a randomly chosen fixed charset (yes, just using UTF-8 is
randomly chosen).

ICY streams are also changing charset between updates at will.

Generally speaking I would strongly recommend to migrate away from it.

With best regards,
