That really shouldn't be necessary. When calling COM objects from FoxPro as the ANSI FoxPro COM Interop APIs automatically convert strings to Unicode. And that should work **as long as the active CodePage supports the characters it's trying to assign**. If the string has values that are not valid for the current CodePage the input is hosed before it ever goes to COM. If you are in a Russian CodePage I don't think the Western Umlauts are valid and if printed would print `?`.

It's hard to say based on the original description that Andrus posted but it sounds to me he's running in a non-Western Code page and trying to send Western characters, which simply won't work unless you switch code pages and convert to binary strings or UTF-8.
