@chenghao-intel Thanks for your pointer: that should fix the problem.
Here is updated test case that works now on my local and I am going to push it

checkEvaluation(Strlen(Literal("\uF93D\uF936\uF949\uF942", StringType),
"ISO-8859-1"), 4)
checkEvaluation(Strlen(Literal("\uF93D\uF936\uF949\uF942", StringType),
"UTF-8"), 4)
checkEvaluation(Strlen(Literal("\uF93D\uF936\uF949\uF942", StringType),
"UTF-16"), 2)
checkEvaluation(Strlen(Literal("\uF93D\uF936\uF949\uF942", StringType),
