MPC-BE crashed on start up when playing media file

[aloola18]

my mpc-be crashed when I play file in the folder with the name:

【MMD】MAMAMOO - gogobebe

turning off AVSF and I can play the file normally. avsf ver 1.1.6

I use the plugin with SVP.

Are you suggesting if you change the folder name without changing anything else, it would not crash? And what if you put a video that does crash into that folder will it start to crash?

Can you provide log?

[aloola18]

changing only the folder name and it wouldn't crash anymore. https://cdn.discordapp.com/attachments/290709370600423424/863724065922744330/mpc-be64.exe.1.5.8.6302.dmp here is the dump file

The video file https://1drv.ms/u/s!AvZFs4-QK6gCgYsmrBQhhHXcCKX5QA?e=jranas

The root cause is basically a problem in AviSynthPlus that can't handle Unicode characters (e.g. 【) in file path, described in https://developercommunity.visualstudio.com/t/stdfilesystempathgeneric-string-throws-an-exceptio/721120. This problem doesn't happen in MPC-HC because it would instead set current directory to it's executable's folder. There is nothing I can do.

You can do two things: 1) Open an issue to AviSynthPlus to suggest them handling these Unicode characters in their future versions. However, since SVP can't use any AVS+ version beyond 3.5.1 right now, it won't solve your problem. 2) Switch to the VapourSynth variant, which handles the Unicode characters and is already supported by SVP.

Of course, you can also rename the video directory/filename to not have these characters.
