I have come up with a small way to read and correctly display form data with non-ascii characters in OpenMCL, which does not support Unicode. Or at least, I think I have. There may be good reason not to do things this way - someone let me know if that is the case.
First, I redefined escape-for-html so that it would return NIL if its parameter was NIL instead of generating an error. Then I just used escape-for-html instead of escape-string-all when displaying the parameter (I was just playing around with the tests that came with TBNL here).
My question is this: are there problems that can arise with the use of escape-for-html that escape-string-all avoids? If not, then I'll just be using this.
