I found that the software displays text which uses the Unicode "\u+..." is displayed wrong. I made a test-file and save it as test_2004.dwg; test_2007.dwg and test_2010.dwg. Only 2004 is correct, the others are wrong.
Hello Peter. The Unicode symbols stored "as is" in CAD files starting from AC1021 (2007) version. The DWG 2004 file still contains Unicode symbols as "\U+...". We're working on CADView 8 release that will provide full Unicode support.
