NOTE: Escaping a leading digit ensures that output corresponds with pattern text which may be used after a \0 character escape or a DecimalEscape such as \1 and still match S rather than be interpreted as an extension of the preceding escape sequence. Escaping a leading ASCII letter does the same for the context after \c.
ii. Let numericValue be the numeric value of c.
iii. Let hex be Number::toString(𝔽(numericValue), 16).
iv. Assert: The length of hex is 2.
