ffprobekit does not recognise non-ascii characters

[theli]

Description
Audio mp3 files with id3v2 tags filled in Chinese or Japanese in UTF are returned garbled when using ffprobekit method FFprobeKit.getMediaInformationAsync and latest 4.5 version for iOS. I have tried obtaining metadata with getLogs() and got same problem. Running ffprobe on MacOS returns valid tags metadata.
Expected behavior
Tags written in unicode non-ascii characters should be extracted properly.

Environment

• Platform: iOS
• Architecture: any
• Version 4.5
• Source branch (if applicable) [e.g. master, development, v4.4]
• Xcode version 12.4, 13
• Cocoapods version 4.5

Other
Add any other context about the problem here.

Can you provide a sample file to reproduce this issue?

try to ffprobe this url https://filedn.eu/lDgxtlj7H6nBDflef6kzNq7/tmp/03_jp_sample.mp3
Note, that I have tried ffprobe-kit on iOS only with remote url and got the issue. I am also attaching the file here.

Thanks. I managed to see the problem locally. Though I'm not sure about the reason yet.

In FFmpegKitConfig.m we are using NSUTF8StringEncoding to convert the strings from char* to NSString. I suspect those Unicode characters are lost during that conversion. We need to debug this.

Fixed on the development branch.
