# title:        Add built-in functions UNICODE_CHAR and UNICODE_VAL to convert between Unicode code point and character
# decription:   
#                   NB. Only basic checks are peformed here.
#                   This test mostly will be re-implemented later in order to check more complex cases.
#                   Lists of unicode characters and their codes:
#                       https://en.wikipedia.org/wiki/List_of_Unicode_characters
#                       https://gist.github.com/ngs/2782436
#               
#                   Checked on 5.0.0.29.
