The previous text suggested that the \U escape sequence form could only be used with codepoints starting at U+10000, and that both \u and \U forms had to use uppercase hexadecimal characters. This commit updates to correctly reflect that \U escapes can use any codepoint (U+0 to U+10FFFF) and the hexadecimal characters are case-insensitive.
