Question about renaming a file after nokia5800 is upgraded to V21

I believe many of my colleagues who updated nokia5800 to V21 were teased by its renaming. In this case, after being upgraded to V21, all files and folders cannot be renamed to Chinese, otherwise, the system will not be able to identify the file. You can take the card out to your computer (in Windows) and read it (unidentifiable/read). I checked it online, most storage cards are missing.
Because the monks suffer from an important file, they do not plan to get stuck, and they will not be nervous to "commit suicide before being convicted "...

If you see this article, and you are still saving your file (No, your file is still saved), go to Linux and use the "large-capacity storage" Mode for USB connection.
When mounting, remember to add the option-O iocharset = gb2312 for Chinese recognition.
It's all done!
