Arabic suffix or prefix

HI

the code below is aiming to remove Arabic prefix but there is erroe

str = native2unicode('اليومين','UTF-8');

prefix=native2unicode( 'ال','UTF-8');  % The prefix to remove
suffix = 'ين';  % The suffix to remove

str = strrep(str,prefix, '')

[Asad (Mehrzad) Khoddam]

What version of Matlab do you have?

It works fine for me
