- Allow opening of non-latin filenames on Windows, by using the non-standard _wfopen(), meaning that the IfcSpfStream no longer relies on a std::istream but a FILE* descriptor
- Allow accessing entities by GlobalId
- Some more support for writing back IFC
- Prefix EXPRESS Enum values to avoid collisions
- Fix a bug in the SenseAgreement of Cartesian trimmed curves
- Use straight line segment in case point projection failed on trimmed curve
- Add epsilon to polylines and -loops point equality test
- Decompose a convex polygonal bounded halfspace into several unbounded halfspace and process only if they operate on a volume larger than some epsilon
- No longer fail connected facesets if a single face is invalid
- Updated IfcBlender for compatibility with Blender 2.62
- Added additional test files
- Automatic tests for several well known IFC files on the Internet
- IfcBlender: Make visibility in render consistent with 3d view
- Some compatibility for Ifc2x files with IfcShapeRepresentations and RepresentationIdentifier 'IAI'
A real solution could be to compile IfcGeom into a dynamic library and compile multiple versions of _IfcImport.so for different configurations which are selected based on sys.maxunicode
Another alternative would be not to rely on strings when exchanging textual data but vectors of int that contain the string character codes
