Moneris Hosted Tokenization, how to get label to display apostrophe?

Similar to this question

I need to display an apostrophe in the label for example:

<label for="monerisExpInput", class="monerisInputLabel" id="monerisExpLabel">Date d_expiration (Format - MMAA)</label>

But despite what I send in the request, including this:


I get:

Date d_expiration (Format - MMAA)

Any assistance would be appreciated, thank you.
