@@ -487,9 +487,19 @@ Strings can contain the following escape sequences:
+---------------------+---------------------------------+
| ``\\`` | Backslash |
+---------------------+---------------------------------+
| ``\uXXXX`` | Unicode codepoint ``XXXX`` |
| ``\uXXXX`` | UTF-16 Unicode codepoint |
| | ``XXXX`` |
| | (hexadecimal, case-insensitive) |
+---------------------+---------------------------------+
| ``\UXXXXXX`` | UTF-32 Unicode codepoint |
| | ``XXXXXX`` |
| | (hexadecimal, case-insensitive) |
+---------------------+---------------------------------+
There are two ways to represent an escaped Unicode character above 0xFFFF:
- as a `UTF-16 surrogate pair <https://en.wikipedia.org/wiki/UTF-16#Code_points_from_U+010000_to_U+10FFFF>`_ ``\uXXXX\uXXXX``.
- as a single UTF-32 codepoint ``\UXXXXXX``.
Also, using ``\`` followed by a newline inside a string will allow you to continue it in the next line, without
inserting a newline character in the string itself.
