Add support for the \uXXXX escape sequence
Submitted by Evgeny Bobkin
Created attachment 249841 patch proposal for the \u escape character support
Vala does not support the \u escape sequences.
So the compilation ends logically with: error: invalid escape sequence
Moreover, there is no validation of the supported escape sequence \xYY, where Y represents a hex digit.
