The textcyr test did not work anymore, since the output of
"CYRILLIC SMALL LETTER VE" changed from \textcyr{\char226} to \textcyr{\cyrv}.
The the old version is now converted to ERT. In theory it could also be
converted to "CYRILLIC SMALL LETTER VE", but this would mean to maintain an
extra list, which is not worth the effort.
\textnumero\texttrademark
from textgreek and textcyr:
-\textgreek{>a}\textcyr{\char226}
+\textgreek{>a}\textcyr{\cyrv}
from subscript:
\textsubscript{4}
