A designation like ESC ( A (UK) isn't one of the two it handles ("0" and "B"), so it stores nil as that slot's charset. The next character written then fails (cl-assert charset) in eat--t-write. Since writes run off the output-queue timer, it repeats once per output chunk. An agent terminal that emits one of these bytes throws "cl-assertion-failed (charset)" hundreds of times and stops rendering. I added filter-args advice on eat--t-set-charset that coerces a nil charset to us-ascii before it's stored, so an unmapped designation falls back to plain ASCII instead of wedging. Patching the vendored pcase would be cleaner, but a package update reverts it. The advice loads with eat, since the target is an internal function.
