Is there a function that will test if the input is char OR string OR cellstr?

Given many MatLab functions can easily handle strings, cellstrings and char arrays in their stride, is there a function which allows me to test if my variable is any of these?
I am aware that a simple function would be
function output = isText(myVar)
output = isstring(myVar)||ischar(myVar)||iscellstr(myVar);
end
but I feel like there should already by a function for this which is highly optimised?
I am sorry if this has been asked before, but if it has, the keywords are so used that this question is nowhere to be seen.

Thanks. I was assuming that, given many MatLab functions can take any of those 3 input types in order to produce the same thing, that there would be some kind of underlying type that you could test for to catch all 3 in one statement.
I guess this must be what happens when you pass the MatLab functions the data. shrug
Thanks

You've made that function. If you look at the "See also" section of "help iscellstr", you don't see any other related functions.
