Converting text to Wingdings in formula

I have for loop that is reading through an array from a multi value parameter passed by the user. The loop has a chr(253) in it. The problem is, the values from the user are not Wingdings. So, if I edit the filed as font type = Wingdings, then the test from the parameter is not readable.

Is there a way to "wrap" a Chr(253) in the middle of CR Syntax to convert it to Wingdings while leaving the rest of the code in Arial font?

strVal := strVal & chr(253) & " " & {?TestMulti} [intLoop];

to something like:

strVal := strVal & (crWingdings(chr(253)) & " " & {?TestMulti} [intLoop];
