%%functions added to utf8.erl  which already exports [encode/1, decode/1]
-export([list_to_uXXXX/1,binary_to_uXXXX/1]

%list into unicode escaped javascript form 
list_to_uXXXX(Str)->
 lists:flatten[io_lib:format("\\u~4.16.0B",[X]) || X <- Str].

%% first converting to list,then to uXXXX form
binary_to_uXXXX(Bin)->
 list_to_uXXXX(decode(Bin)).
