Special Characters allowed when SharePoint List in List Url

Question

Are there any set of Special characters that are not allowed when the list is created and the url is generated for the same. For e.g. When i create list say A&B the url when generated for the list does strip the & from it. Do we have anything documentation which lets us know that certain number of special case characters are not allowed

Answer 1

From this: Acceptable characters in SPList 'title' fields

Every List should match to an unique directory with a full url path.

When you create a new list, SharePoint will assign the name of directory based the value of the title. The name of the directory can only include non-special characters like 0-9,a-Z  and “”, but the character “” can’t be as starting.  

The list name/title is the same as your typed.

If the list title include the special characters, SharePoint will remove all characters.

If the rest start with the “_”, this character also will be removed.

The rest will be as the name of the directory.

At last if the rest is blank, the name will be replaced by “list”, if the “list” existed, use the “list1” and so on.

From this: Information about the characters that you cannot use in site names, folder names, and file names in SharePoint

Section "Folder Names"

You cannot use the following characters anywhere in a folder name or a server name:

• Tilde
• Number sign
• Percent
• Ampersand
• Asterisk
• Braces
• Backslash
• Colon
• Angle brackets
• Question mark
• Slash
• Pipe
• Quotation mark

You cannot use the period character consecutively in the middle of a folder name.

You cannot use the period character at the end of a folder name.

You cannot start a folder name with a period character.

If you use an underscore character (_) at the beginning of a folder name, the folder will be a hidden folder.

Additionally, a folder that contains the string "vti" is reserved by SharePoint, and isn’t supported.

Answer 2

The disallowed characters are here. As long as the name or url doesn't have these you should be good.
