ASCII Control Characters in DXF Files

SAVEAS handles ASCII control characters in text strings by expanding the character into a caret (^) followed by the appropriate letter. For example, an ASCII Control-G (BEL, decimal code 7) is written as ^G. If the text itself contains a caret character, it is expanded to caret, space (^ ). OPEN and INSERT perform the complementary conversion.
