The value n is a string of characters that provides the From list for Identifier Translation mappings. The maximum length of the string is 256 characters. The default string is:
~ `@#$%^&*()_+-=[]\{}|;':"",./<>?".
These mappings filter/modify valid SQL identifier characters when translating SQL identifiers into Objects identifiers. When converting an SQL identifier to an Objects identifier at runtime, the characters in the From string are converted to the characters in the To string. Also see IdTrxTo.
