When translating a document name to a url path segment the following rules are used:

• Control characters (ASCII / Unicode / ISO/IEC 8859-1 codes below 0x1f and between 0x80 and 0x9f such as tabs, carriage return, line feeds, end-of-text, bell, etcetera) are removed;
• A non brakable space is converted into a regular space;
• Multiple spaces are merged into a single space;
• Spaces are converted to hyphens;
• All common printable characters (ASCII / Unicode / ISO/IEC 8859-1 codes in the range 0x21 and 0x7f) are are used as-is, unless there is a replacement as specified in table 1.
• All letters from the Unicode Latin-1 Supplement block are converted to their lowercase base letter, e.g. 0x00c0 Latin Capital Letter A with grave, is converted to "a".
• All letters from the Unicode Latin Extended-A block are converted to their lowercase base letter, e.g. 0x0100 Latin Capital Letter A with macron, is converted to "a".
• Other special characters (ASCII / Unicode / ISO/IEC 8859-1 codes not in the range 0x21 and 0x7f) that are not listed in table 2 or table 3 are converted to lowercase;
• Leading spaces and ending spaces are removed.

All rules and translation tables are applied, not just the first matching rule. So if a rule indicates that a character is converted into a space, and another rule specifies that spaces are converted to hyphens, than the character is converted into a hyphen

The following translation tables for printable characters are used:
