Hi,

   I'm not sure, but it seems like I am no longer able to write Metadata using unicode text for my Japanese, Chinese etc. customers. Here is my code:

    ' Set Information of PDF
    '-----------------------
    If fUnicodeUser Then
        '1 = Author
        rtn = oPDF.SetInformation(1, oPDF.ToPDFUnicode(Author))
        '2 = Title
        rtn = oPDF.SetInformation(2, oPDF.ToPDFUnicode(Title))
        '3 = Subject
        rtn = oPDF.SetInformation(3, oPDF.ToPDFUnicode(Subject))
        '4 = Keywords
        rtn = oPDF.SetInformation(4, oPDF.ToPDFUnicode(Keywords))

    Else
        '1 = Author
        rtn = oPDF.SetInformation(1, Author)
        '2 = Title
        rtn = oPDF.SetInformation(2, Title)
        '3 = Subject
        rtn = oPDF.SetInformation(3, Subject)
        '4 = Keywords
        rtn = oPDF.SetInformation(4, Keywords)

    End If

   When I recover the data from QuickPDF, it looks OK, but when I view the information from within Adobe's Reader or FoxIt's Reader, I see garbage.

   Here is an example of what I set and recover using QuickPDF:

Author -サルエルパンツ

Appears like this in PDF Reader and FoxIt Reader (with Windows set to Japanese and the Reader too):

Author -ƒTƒ‹ƒGƒ‹ƒpƒ“ƒc

Any ideas?

I am a Japenese and I am also annoyed by the samge kind of characters garbage.

The byte order of サムエルパンツ　in Shift_JIS(most common Japanese character codes) is

0x83 54 83 80 83 47 83 8B 83 70 83 93 83 63. If these byte order is interpreted as Windows-1252, the output turns out to be ƒTƒ‹ƒGƒ‹ƒpƒ“ƒc.

There is the same kind of phonomena in both SetFormFieldValue and AddGlobalJavaScript as far as I test the trial: 7.1.6.
