    <td colspan="2"><p>
 When&nbsp;using TripleStroe.LoadFromFile to import triples file, if&nbsp;it contains literal with uppercase sub language tag, a query cannot match the literal.</p>
<p>
 The following case&nbsp;gets empty result.</p>
<p>
 File:</p>
<p>
 _:a&nbsp;&lt;urn:p&gt; <a href="mailto:&quot;test&quot;@en-US">&quot;test&quot;@en-US</a>.</p>
<p>
 Sparql:</p>
<p>
 select * where { ?s ?p <a href="mailto:&quot;test&quot;@en-US">&quot;test&quot;@en-US</a>. }</p>
<p>
 or</p>
<p>
 select * where { ?s ?p <a href="mailto:&quot;test&quot;@en-us">&quot;test&quot;@en-us</a>. }</p>
<p>
 or</p>
<p>
 select * where { ?s ?p ?o. filter (str(?o)=&quot;test&quot;&amp;&amp;lang(?o)=&quot;en-us&quot;) }</p>
<p>
 but following query can&nbsp;work properly.</p>
<p>
 select * where { ?s ?p ?o. filter (str(?o)=&quot;test&quot;&amp;&amp;lang(?o)=&quot;en-US&quot;) }</p>
<p>
 &nbsp;</p>
<p>
 If the triples are inserted by sparql update, the above queries can work properly.</p>
<p>
 I guess the sparql engine&nbsp;normalizes the language tag&nbsp;to&nbsp;lowercase but imports way&nbsp;does not.</p></td>
