Hello,

doing something like:


s = u“a unicode sting”
print s


results in an TypeError in recent 11.1.64. So, no unicode strings in houdini? This is especially annoying when using PyQt QString api v2…

Cheers

Sebastian

You could just define a function that encodes it before printing.

def printU(s):
print s.encode('utf-8')

EDIT: If it's the actual print that breaks.

Thats what I am doing, but isnt it a little bit strange not being able to print unicode (is it the same on linux?!)

It depends on what console you are using. Anyways its not really a Houdini problem. Search for it on stackoverflow and there are loads of threads.

Sorry, I dont get what you are saying… From what I see it is a Houdini problem (bug or known limitation in 11.1.64):

>> print u“hello world”
Traceback (most recent call last):
File “<console>”, line 1, in <module>
File “CPROGRA~1/SIDEEF~1/HOUDIN~1.67/houdini/python2.6libs\hou.py”, line 25114, in write
return _hou.ShellIO_write(*args)
TypeError: in method ‘ShellIO_write’, argument 2 of type ‘std::string const &’

Using Fedora 12

In an interactive python shell:
>>> print ‘Porks Werfect’
Porks Werfect
>>> print u'Porks Werfect'
Porks Werfect

In Autodesk Maya Script editor:
print ‘Porks Werfect’
Porks Werfect
print u'Porks Werfect'
Porks Werfect

In sideFX Houdini python shell:
>>> print ‘Porks Werfect’
Porks Werfect
>>> print u'Porks Werfect'
Traceback (most recent call last):
File “<console>”, line 1, in <module>
File “/opt/sidefx/hfs12.1.185/houdini/python2.6libs/hou.py”, line 28613, in write
return _hou.ShellIO_write(*args)
TypeError: in method ‘ShellIO_write’, argument 2 of type ‘std::string const &’

I'm not sure, but at a quick glance and not with full access to _hou.so, this in there within in reference to the error above :

invalid null reference in method ‘ShellIO_write’, argument 2 of type ‘std::string const &’

So perhaps it's only when unicode characters are somehow returning None, that this error comes up?

Nothing major, but it does require most multi-application debug verbosity to be modified explicitly for Houdini in order to get the full printout, so any insight into what the actual bug is will be helpful.
