> Any comments? Personally I think something like that sounds like a good idea, it should probably make a warning (at least to the log, probably console as well) presumably most of the time it would "just work" but if the "active character" implementation of the encoding is mapping that slot to an arbitrarily complicated TeX construct, then presumably just letting the character go through xetex as a native unicode character may do something different, and it may be better to flag that possibility in the log file.
