With the kind help of Grinnz on #perl-help, we determined that the
document you sent causes the following error:

    "Can't interchange noncharacter code point U+FFFF in position 46198"

According to the documentation for Unicode::UTF-8 [1], the use of that
codepoint is not allowed in open interchange of Unicode text data

Kind regards,
Felix Lechner
