This is what you should have in your list:
1> Text = [16#442, 16#435, 16#43a, 16#441, 16#442].
[1090,1077,1082,1089,1090]

You can convert it to utf8 for output

2> xmerl_ucs:to_utf8(Text).
[209,130,208,181,208,186,209,129,209,130]

And you can reverse it and convert that to utf8.

3> xmerl_ucs:to_utf8(lists:reverse(Text)).
[209,130,209,129,208,186,208,181,209,130]
