- Add support of the control directives ( "\X2\" "\X4" "\X\" "\P*\" "\S\"); - Make param "read.stepcaf.codepage" base for conversion inside StepData instead of CAF; - Rename "read.stepcaf.codepage" to "read.step.codepage". - Add ISO 8859-1 - 9 code pages for conversion - Add Resource_FormatType_NoConversion format type, that indicates non-conversion behavior - Update old test cases that contain control directives
