Select BinHex if document contents will be BinHex-encoded. BinHex is a common ASCII encoding method for binary data.
Note:
Base64 and BinHex
document data for advanced document processor do not contain any line wrapping.
For Base64, this would be \r\n (CRLF), which would be escaped as {{\X0D\\X0A}} in an HL7 message.
If line wrapping is used for Base64, it must be the default (76-character lines) or else the document may not be created properly.
Any escaped characters in document data are ignored for Base64 and BinHex (plain text are not affected by these changes).Currently, there is no legitimate reason to escape any character that is valid for Base64 or BinHex.
