When writing for technical audiences, there are various ways to type Unicode representations, but they all seem to be Hexadecimal:
\uFFFF- From C# / Java Strings
\U0000FFFF- From C# / Java Strings
However, Unicode can also be specified in decimal, and can be entered both ways in XML Entities:
While I could just (kind of) use
\u65535, this does make something that is already defined as specifically hexadecimal and abuse it, and also could cause problems - is
\u1111 decimal or hex?
So - are there any programming languages that allow similar ways to denote Unicode characaters by decimal, or common shorthand conventions for specifying Unicode in decimal notation for technical audiences?
