WIRIS editor is committed to fully support the symbols in its toolbar, and in western keyboards (ISO latin-1).
For symbols not in its toolbar, WIRIS editor relies on the fonts installed in your server or your browser. Today there exists no single font that has all the Unicode symbols. WIRIS editor server uses parts of STIX fonts, which has the better coverage for Math symbols.
