<%def> and <%call> with unicode string as argument

[sqlalchemy-bot]

Migrated issue, originally created by Anonymous

Can't use u"unicode strings" as arguments in <%def> and <%call> tags.
Tested with SVN revision 224.

## -*- coding: utf-8 -*-
<%def name="bello(foo, bar)">
<b>Foo:</b> ${ foo }<br>
<b>Bar:</b> ${ bar }<br>
</%def>
<%call expr="bello(foo=u'árvíztűrő tükörfúrógép', bar=u'ÁRVÍZTŰRŐ TÜKÖRFÚRÓGÉP'">
</%call>

will raise
