-  copy a string from one character set to another

-  SYNOPSIS
-    copy_and_convert()
-    to			Store result here
-    to_cs		Character set of result string
-    from		Copy from here
-    from_length		Length of from string
-    from_cs		From character set
-
-  NOTES
-    'to' must be big enough as form_length * to_cs->mbmaxlen
-
-  RETURN
-    length of bytes copied to 'to'
