Reading spaces in the filename

According to the article above though Windows now supports NTFS format, the SD card still uses FAT format. Some character was added, I hope this solves the issue #3

Unless I misunderstand, the only thing this PR does is disallow exclamation points (ASCII code 0x21) in filenames. If that's really what you intend to propose, then you should make that very clear in the commit/PR message, as well as providing your reasoning for this change. "Some characters are added" is not an accurate description.

#3 is about allowing extended ASCII and spaces in filenames. This PR does not do any of that, so definitely should not be considered to solve #3.

okay, shall I close this PR then?

If you think this is a change that needs to be made, then you should leave it open, but you need to explain the purpose.

A lot of file names have spaces and it would be great if they could be recognized easily

[per1234]

Please edit the commit and PR messages to make it clear that is the purpose.

Have you tested to be sure that this change causes the library to allow spaces in file names?

Hey sorry, This patch doesn't solve anything, I had an NTFS format Sd card, which was working after this patch, but I realized that most of the SD card is FAT format, which doesn't support this patch. I will close this PR, I really sorry to waste your time, I promise, not to repeat it again!
