How to escape right parenthesis in variable? - thymeleaf

Question

How can I escape a round bracket (right parenthesis) without closing it in a fragment?
"fragments/questionaire :: questionaire('00001_c-1',
${
{
'...',
'...',
'First 1) ...'
}
},
${
{
'...',
'...',
'...'
}
},'[0,2]')"
Kind of same effect is if keyword new is somewhere in the string.
already tried: 'First 1\) ...' ) ) inside utext
I use it to iterate over an object with questions and hints like:
th:fragment="questionaire(key, questions, hints, rightIndex)"
It's inside a form
<div th:each="aquestion, iterStat : ${questions}" th:with="qid=${key}+'_q-'+${iterStat.index},name='rb-'+${key}">
<div>
<input type="checkbox" th:name="${name}+${'_q-'+iterStat.index}" th:value="0" th:data-s="${iterStat.index}" th:id="${qid}" autocomplete="off" th:checked="${bucket.read('questionaire.'+name+'_q-'+iterStat.index)}==('' + 1)"/>
<label th:for="${qid}" th:text="${aquestion}"></label>
<input type="hidden" th:name="${name}+${'_q-'+iterStat.index}" value="0">
</div>
<div class="hint" th:id="${qid+'--hint'}" th:text="${hints[iterStat.index]}"></div>
</div>
<p class="submitContainer">
<button th:data-qvalidate="|quest${key}|" th:text="#{q.check}">Check</button>
</p>

Following on from my most recent comment in the question...
The least-worst solution I have is to create a Java string variable and add that to your model:
model.put("cp", ")");
where cp means "close parenthesis".
Then you can create a fragment parameter like this:
|foo 1${cp} bar|
And that passes the string foo 1) bar to the fragment without that "selector syntax" error you are currently getting.
<div th:replace="fragments/frag.html :: frag(|foo 1${cp} bar|)"></div>
And my fragment is just this:
<div th:fragment="frag(key)">
<div th:text="${key}"></div>
</div>
I would be happy to learn of a better solution.
