The item will be added to the section of the User dictionary specified by pSection.
User dictionary items are UNICODE strings and they must be no longer than DOC2_MAX_UD_ITEM_LENGTH characters, the function will ignore the extra characters (including the terminating zero). They may contain spaces and punctuation characters.
When adding a new User dictionary item its uMask also has to be specified. An item can be added either as a literal or as a regular expression. When uMask is DOC2_USER_DICT_REGULAR_EXPRESSION, the User dictionary item will be evaluated for conformance during the checking of the recognized result.
