text: Historically, the originally proposed use of 0x60 in the international 7-bit coded character set was as a grave accent (ISO TC 97/SC 2 meeting, October 29-31, 1963), and only later its meaning was extended in the US implementation of the standard to also cover the use as a left single quotation mark (CACM 8(4)207-214, 1965).
