UTF issue with ifc import

[hardeeprai]

On trying to import

https://raw.githubusercontent.com/Great ... TDP202.ifc

file I get following error:

Exception (Sat Nov 10 20:18:02 2018): UTF8 conversion failure at PropertyString::getPyObject()
Traceback (most recent call last):

<type 'exceptions.UnicodeEncodeError'>: 'ascii' codec can't encode characters in position 0-10: ordinal not in range(128)

What could be the issue?

Looks some utf issue as well.

ifcopenshell.version is : '0.5.0-dev' and other details is:

I did a series of fixes yesterday in the IFC importer/exporter related to python3 and encoding. This file now opens fine for me... I suppose the cause was solved together...

I still got similar error, on importing following file:

freecad-daily is already the newest version (0.18~beta1+git201811101427~ubuntu16.04.1)

which suggests that it was built on Nov 10 2018, while as per following (About FreeCAD) release date is 2018/11/08 19:56:21 (this is not copied from "copy to clipboard" from "About FreeCAD"). This is the same version, which is built about 10 hours ago, as per:

I still got similar error, on importing following file:

On trying other file: https://raw.githubusercontent.com/Great ... TDP202.ifc as reported earlier, getting same file. System hangs I need to kill application.

Also see name of site and project in screenshot.

At least to others have reported similar issue.
It looks to me like the only common denominator is various versions of Ubuntu.

Strange, I don't get this error here. But my freecad version is now switched to python3, I'll rebuild a python2 to test.
The Schependomlaan file takes about one hour to import here on my machine, and crashes at the end. But it's a really big file. I'll do some more testing with it, see if I can optimize things a bit...

So real testing begins

FreeCAD will be maturing fast in BIM

Yes, this file is a very good "target": We should be able to import it reasonably fast, and there should be no problem in working with files of that kind of complexity in FreeCAD.

Schependomlaan file took about 3 minutes to check-in on BIM Server at gdy.club/BIM

If anyone wish to have account there (for limited experimentation), can create account there and send PM for more access / privileges.

It takes about 5 seconds in Ifc++. But that's not a very good comparison, because ifc++ does a very simple import. But nevertheless, there is a huge difference. I'll also test in other BIM apps such as Revit and ArchiCAD, that should give us a good idea of where we should arrive...
