title: REGEXP in Android SQLite
body: <p>I am trying to get a REGEXP to work with android SQLite in the contacts database. What I am trying to do is do whole word matching for the contacts display name to look for words such as "uncle" or "aunt" even when the display name may be something like "uncle sam" or "aunt julie". However whenever I try using REGEXP I get the error</p>
  
  <pre><code>android.database.sqlite.SQLiteException: ICU error: uregex_open(): U_ILLEGAL_ARGUMENT_ERROR (code 1)
  </code></pre>
  
  <p>This is a simplified version of what I am trying to do in the query:</p>
  
  <pre><code>whereBuffer.append(ContactsContract.Contacts.DISPLAY_NAME).append(" REGEXP ").append("'[[:&lt;:]]uncle[[:&gt;:]]'");
  </code></pre>
