Fixed crashes when trying to open YouTube videos with emojis

[borislav-draganov]

Noticed that when I try to sync YouTube videos on MPC with youtube-dl.

If the video title contains emojis it starts disconnecting and reconnecting infinetely.

Stacktrace:

builtins.ValueError: string too long (111, maximum length 109)

Added filter for non-ASCII characters to solve the issue.

I remembered a friend had the same issue with VLC (on Windows) so that's why I updated it to include all players.

Want me to have only for MPC-HC?

I've able to reproduce on MPC-HC (64-bit) 1.7.13 on Windows 10 by sending the following chat message: 😂😂😂😂😂😂 - It generates the error: builtins.ValueError: string too long (19, maximum length 14).

The change you proposed means it prints nothing at all when I send those emojis, but alternatively you can change ('strMsg', ctypes.c_wchar * (len(message) + 1)) in mpc.py to ('strMsg', ctypes.c_wchar * (len(message.encode('utf-8')) + 1)) to fix it. Does that solve the issue for you?

I've not been able to reproduce the issue on VLC Maybe your friend could provide specific reproduction instructiong, including which version of VLC and Syncplay they are using.

Seems like the issue is now resolved 👍
