An extra reason to get error CS1009

[RexJaeschke]

Type of issue

Missing information

Description

Here's an extra case to add to the example:

string s = "\U00110000";

The escape sequence is well-formed; however, it represents an out-of-range value. Specifically, Unicode code points above U+10FFFF are invalid and are not supported.
