Hi all. I have a web server running on an ubuntu linux system. But as I thought today I just realized I know next to nothing about characters which are legal in naming directories. Searching didn't help in the sense that I don't even know if there is a difference between the restrictions of folder names on the web and folder names on a local machine.
Basically I am asking:
-What characters are allowed when naming a directory? Punctuation? Standards Symbols? Chinese? These "pictures": ☺ (side question: what are these types of characters referred to as officially)? ™∞§¶¡•£ªº©´†œ¥? etc
-Even if they are allowed, should I not use them? And why?
-Can all of these legal characters be stored in a MySQL database?
-Are different browsers not able to access the folders with certain characters?
-What is the max folder name length?
-Do all of these questions vary for whatever OS you are hosting on?
The reason I ask such a question is that Id like users to be able to create folders on the site based on a string they type in, but I have no idea which characters to restrict.
Thanks! I know this is a lot, sorry.
