This is a terrible idea! You're not avoiding anything, you would still have to escape these characters in CSV because it's entirely possible (in fact, almost certain) that someone will want to use the character itself in a CSV file. Besides, it's arguably a GOOD thing that the delimiter in CSV (the comma) is such a common character, because it forces all parsers to properly support escaping and quoting. If it used some sort of unique character that was almost never used except in CSV, then 99.9% it would work without correct escaping, but the 0.01% when someone entered "you should use the character X to separate fields" as a column it would fail, and those cases are much more likely to slip through the cracks. Also: the whole point of CSV is to be human readable. There's no obvious way to render "Record separator" on screen, and the format would essentially become a binary format.
