I now realize I should have suggested a solution in the comment to
your issue ticket in bugzilla.
EL has no notion of char, it only knows about "StringLiterals", which
is what 't' becomes in:
<c:if test="${tChar == 't'}">
If your immediate interest is evaluating this equality condition, I'd
use a String in the request.setAttribute, one that consists of one
character "tChar".
Let me know if you have other questions.
