Commas, quotes, colons, newlines, and hyphens (JSON and YAML separators) can occur in content as well. How is that any different from separators occurring in csvs? In practice, I used TSVs a lot, as tabs do not usually occur in most data. Alternatively, you could use pipes (|) or control characters as field or row separators.
