Description
Assembles a formatted Unicode string using a format string and an array of arguments.
This function formats the series of arguments in the open array Args into a Unicode string. Formatting is controlled by the format string Format; the results are returned in the Result parameter.
For information on the format strings, see Format strings.
The first form of WideFmtStr is not thread-safe, because it uses localization information contained in global variables. The second form of WideFmtStr, which is thread-safe, refers to localization information contained in the AFormatSettings parameter. Before calling the thread-safe form of WideFmtStr, you must populate AFormatSettings with localization information. To populate AFormatSettings with a set of default locale values, call TFormatSettings.Create.
