The ease of typing a character should only matter for artisanal, hand-typed files.

I agree. So if we don't need this hand crafted and for human consumption, we may as well just use some TLV or LV encoding instead of the CSV madness of separators and escaping. CSV is basically designed for hand crafting.

They are also easy to read, perhaps easier than a 'space' or other character. Although this could be because we are just used to seeing data eg CSV in this way
