[reportlab-users] Error using encoding="utf-8" to output RML to PDF

[Robin Becker]

In fact I'm being stupid, if the django is producing mixed stuff somehow then 
the templating software should blow up as bytes (utf8) are added to unicode or 
vice versa.

If on the other hand you declare utf16 in the rml header, but django is 
producing utf8 then you'll likely get this error.

I tried just changing the encoding to utf-16 in the header of one of my test 
files (ie it is a bytes file) and I get exactly this error


C:\tmp>rml2pdf bad.rml
Traceback (most recent call last):
   File "c:\code\rlextra\rml2pdf\rml2pdf.py", line 6511, in <module>
     main()
   File "c:\code\rlextra\rml2pdf\rml2pdf.py", line 6503, in main
     dynamicRml=1
   File "c:\code\rlextra\rml2pdf\rml2pdf.py", line 6147, in go
     parsed = parsexml(xmlInputText,eoCB=_eoDTD)
pyRXPU.error: Declared encoding UTF-16 is incompatible with UTF-8 which was used 
to read it
Internal error, ParserPush failed!

clearly a bytes file cannot be utf16.

This seems to indicate you are actually producing utf8 under some circumstances.
