Problem

-- If you are trying to create a DML map and try to convert a file to XML standard probably you can wonder why when you are trying to escape the quote character \" the result will be " & quot". (without space between & and quot)

"He said \"using quotes in strings is irritating\""

and the result:

Resolution

--There is no bug in the B2Bi, it is just the XML standards, double quote in XML is a special character, thus it is replaced by the entity reference "& quot"

See https://www.w3schools.com/xml/xml_syntax.asp

--If you don't want to follow the XML standards you can try to use a post-processing (JMC for example) to replace the " with the desired character.
