Encloser does not take into account ";" when using ";" as the CSV delimiter

[Fedduh]

I noticed that there is an encloser function. In the comments it states that when using a comma in the field, it will be enclosed by "".

I'm using types.csv with delimiter ";". But if my cell contains ";" it will not enclose them.
I suppose the encloser function should take the chosen delimiter into account (or both "," and ";").

// Rule: Fields that contain commas must begin and end with double quotes.
// .. other rules
function encloser (value: string) {
const enclosingCharacter = /,|"|\n/.test(value) ? '"' : ''
const escaped = value.replace(/"/g, '""')

return ${enclosingCharacter}${escaped}${enclosingCharacter}
}
