    Hi Alex,

    I know XEP currently not support double byte characters.
    But I just try to do some post-processing of XEP postscript output to
    fulfull our need.

    I am trying another way as a workaround.
    Let the chinese characters I tested before pretend to be an ascii string,
    and I encode the string in xml as follows:

    <fo:block>&#xA4;&#x6A;&#xA4;&#x70;&#xB3;&#x71;&#xA6;&#x59;</fo:block>

    but the postscript output is as follows:

    (\000\000j\000\000p\000\000q\000\000Y)

    Every characters have a prefix character \000.
    If I removed all the \000 characters from the above string,
    the result matched the previous encoded string in XML.
    How could you prevent the \000 characters output as above?

    I wish my questions won't bother you too much.

    Hello Pierre,

    Unfortunately, as I mentioned in my previous letter, two byte
    encodings are not supported in XEP PostScript output yet. Please
    follow the announcements.

    Phc> Hello,

    Phc> Thanks for your helpful support!

    Phc> I found the problem of chinese output in pdf was solved.
    Phc> I downloaded the asia font pack for acrobat reader in www.adobe.com,
    Phc> and I choose using the open type font MSungStd-Light-Acro defined in
    Phc> fonts.xml.
    Phc> I found it's fine since the rendering speed was as normal and also the
    pdf
    Phc> size was small.

    Phc> But I still want to handle the chinese output for postscript.
    Phc> Because our postscript printer has some residential chinese fonts,
    Phc> I tried to use the same approach as the pdf one to generate a
    postscript
    Phc> file
    Phc> and then patch postscript file to replace the MSungStd-Light-Acro font
    name
    Phc> with the printer's chinese font name.
    Phc> But problem arised, I found the postscript file's chinese characters
    was
    Phc> different from the original .fo file one.
    Phc> I tried to put four chinese characters for test, i.e. ???? (in hex:
    A46A
    Phc> A470 B371 A659) which is in Big-5 encoding,
    Phc> Our printer's internal chinese font also use Big-5 encoding,
    Phc> but the characters in postscript file become "Y'\\\017 032T\003" (the
    Phc> middle two spaces are two nonprintable characters 90 5C in hex).

    Phc> Could I have any way to force the XEP not alter the chinese characters
    in
    Phc> the postscript output?

    Phc> Hello Pierre,
