Open FileName$ For Output As #fn
Print #fn, vbUTF16BOM; ' first char is the UTF-16 Byte Order Mark
... ' everything automatically converted to UTF-16
Close #fn

To create a Unicode (UTF-8) text file, use the following:

Print #fn, vbUTF8BOM; ' first three chars are the UTF-8 Byte Order Mark
... ' everything automatically converted to UTF-8
Close #fn
