<p class=MsoPlainText>Marco,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText><span lang=EN-US>in CPython reportlab we expect all
strings to be either bytes in utf8 encoding <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>or unicode. I suspect that the default
string encoding in ironpython is <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>something other than that so a lot of
reportlab string handling may be broken.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>Does ironpython support unicode directly
ie u'Hello World'?<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>I would not expect reportlab to work out
of the box with ironpython. PDF doesn't <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>use unicode (normally) and most of the
output is in Adobe specific encodings.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>I don't think the real problem lies in
our use of strange bytes (although that <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>may not help). If the string in question
is the special sequence we use at the <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>beginning of the document then the issue
is deeper since that string doesn't <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>normally require any special
manipulation (ie we expect it to appear literally <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>in the output as a sequence of bytes).
If we are unable to write bytes directly <o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>to a file then many other problems will
also need to be found and fixed.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>This problem also arises in Python 3.x
so may eventually be solved for you.<o:p></o:p></span></p>
<p class=MsoPlainText><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoPlainText><span lang=EN-US>As to why reportlab takes so long to
execute I cannot say.<o:p></o:p></span></p>
