I've recently experienced a problem where by users have entered control code characters into Long text fields. Specifically the ASCII codes
\001, \007, \008, \021 (codes for
Start Of Heading, Bell, Backspace, Device control 1) which are causing havoc in my XML exports since they are not allowed by the XML standard and prevent the XML file from being parsed.
Therefore I would like to cleanse the output as it goes through Views Data Export to prevent bad characters from outputting. As commented below, this sounds like a bug in VDE, however I'm wondering whether I can tackle this issue easily with my own views hooks rather than wait for a new version/patch?
