I like
[`emptyToNull`](https://google.github.io/guava/releases/19.0/api/docs/com/google/common/base/Strings.html#emptyToNull(java.lang.String))
for this, but this isn't a problem or anything.
> rdf:langString argument to text:query silently ignored

> Key: JENA-1438
> URL: https://issues.apache.org/jira/browse/JENA-1438
> Project: Apache Jena
> Issue Type: Bug
> Components: Jena
> Affects Versions: Jena 3.5.0
> Environment: N/A
> Reporter: Code Ferret
> Priority: Minor
>
> Queries of the form:
> {{?s text:query "some string"@lang-code}}
> return no results even when there are matches found by the _equivalent_:
> {{?s text:query ("some string" "lang:lang-code")}}
> {quote}
> Note the above _equivalent_ form is currently valid only if
> {{text:multilingualSupport false}}.
> {quote} See [JENA-1437|https://issues.apache.org/jira/browse/JENA-1437]
> A reasonable fix is to recognize the {{rdf:langString}} case and treat it as
> the _equivalent_ form referring to the {{text:defautlField}}; otherwise, at
> least an error should be indicated.
