I sometimes want to use a function to get Unicode code point notation used in convention like U+0061 (Unicode 15.0, p.968) from Char. Such function is implemented in

and it is easy to write:

unicode_code_point_notation(c::AbstractChar) = "U+" * uppercase(string(codepoint(c), base=16, pad=4))

But I think it is good to have the function in module Unicode.
