-As noted above, Luau implements support for hexadecimal (`\0x`), Unicode (`\u`) and `\z` escapes for string literals. This syntax follows [Lua 5.3 syntax](https://www.lua.org/manual/5.3/manual.html#3.1):
+Luau implements support for hexadecimal (`\0x`), Unicode (`\u`) and `\z` escapes for string literals. This syntax follows [Lua 5.3 syntax](https://www.lua.org/manual/5.3/manual.html#3.1):

 - `\u{ABC}` inserts a UTF8 byte sequence that encodes U+0ABC character into the string (note that braces are mandatory)
