LLVM IR iteself only supports one string ty, which is an array of
i8 (8 bit integers). In your compile you can use utf-8 and any
utf8 string literal can be stored in an i8 array in the LLVM IR.

For example, the LLVM backend for the DDC compiler [0] does this:

   @str = internal constant [4 x i8] c"bar\00", align 8


HTH,
