What scores do your users get? You can check in logs, it looks something like: antimixedutf8.ANTIMIXEDUTF8_HIT info: [antimixedutf8] Client .... hit score XX - taking action And what score did you configure to act upon in the config? |

Oh yeah I see what you mean, the éá etc stuff is in a different unicode block, so for languages like French there are lots of block transitions leading to higher antimixedutf8 scores. We suggest 5-10 and default to 8 but that is quite reachable in ordinary text. Eg with 8 you only need 4 accent characters because you are transitioning back and forth. Pretty dumb oversight. In the old version of the module we also didn't see it as one big block but in that version it was a transition to an "undefined" code page (and back) so didn't count. |
