    I think you mean \u00e1

Why shouldn't \ue1 work?

    > Note that \xe1 does not work for this any more.

    Indeed, this refers to the byte 225 rather than to the char 225.

This needs to be documented.  But is it a good meaning for \x?  It
will rarely be useful this way.  Also, is it an incompatible change?
