Remarks

Set the lCodePage parameter to one of the code page identifiers that are defined for the CodePage parameter of the MultiByteToWideChar function. For more information about this function, see the Windows SDK documentation.

Although most applications now use Unicode (UTF-16) encoding for character data, some Windows desktop applications use character sets based on Windows code pages. A code page assigns international characters to ANSI character codes greater than 127. For more information about code pages, see the Windows SDK documentation.

Convert to Unicode using the Japanese code page, if applicable.

If strLang = "JP" Then
    tmpStr = OleCvt.ToUnicode (str, 932)
Else
    tmpStr = str
End If
