God, I used to work in medical billing, and people would think these file format issues were some kind of scheme. NO they are not. They deal with the obvious problem that clinicians are NOT always programmer friendly, and will put things like tabs in case notes, will use commas etc. At some point you use a delimiter that is much less likely to be used - | - is one of those, not a lot of clinicians use it and you can say, please don't use this. A surprising amount of stuff (at least medical billing side) can be flat file moves, especially if you are billing into lots of different systems. And yes, the idiot new person with a phD says, just quote every field with a ". Great - you program all this up, along with the required escape sequence handling, and then escapes for escapes. \ and / get used a fair bit sometimes already and we are dealing with tons of systems.
