Decodes into “normal” text a string that has been encoded by EncodeQuotedPrintable.
result=DecodeQuotedPrintable(str [, encoding])
|result||String||The result of processing str.|
|str||String||The string expression to be decoded back to its original form.|
|encoding||TextEncoding||Optional: The text encoding of the passed string.|
DecodeQuotedPrintable converts text representations of unprintable characters (i.e., control characters, returns and tabs) back into their original form. It is designed for handling email or usenet messages. It undoes the encoding done by EncodeQuotedPrintable.
The DecodeQuotedPrintable function performs the function in reverse.
DecodeQuotedPrintable can decode strings in which hexadecimal values are represented in lowercase as well as the standard uppercase.
The following example takes the contents of TextArea1 and decodes it. If TextArea1 contains Return character, EncodeQuotedPrintable encodes them and DecodeQuotedPrintable decodes them.
