For your specific example, you can do this,=20
=20
a=3D"_exam@p_ (mailto:exam@p)   Le3|=A7" =20
a.gsub!(/[^A-Za-z0-9]/,'')
p a
=20
You can also eliminate elements you specify in an Array :
=20
class Array
def  eliminate_chars_from_this_array(text)
res=3Dself.dup
res.each{|x|  text.gsub!(Regexp.new(x),'') }
return text
end
end
=20
array=3D["a","@","\247","=E9","\'"]
a=3D"_exam@p_ (mailto:exam@p)   Le3|=A7=E9\247'" =20
a=3Darray.eliminate_chars_from_this_array(a)
p a
=20
Best regards,
=20
Axel=20
