Registration policy. `confusable_check` (default **true**) is the [look-alike name guard](Services#nickserv-accounts): it refuses REGISTER of a nick or channel that mixes alphabets, is built from homoglyphs or styled (fullwidth/math) letters imitating Latin, or hides invisible/bidi characters, while genuine monolingual text — including accented French — passes. Set it `false` for a community that legitimately uses mixed or non-Latin names. Reloadable with `OperServ REHASH`.

Registration (of nicks and channels) refuses **look-alike names** — a name that mixes two alphabets (the classic `аdmin` with a Cyrillic `а`), is built entirely of homoglyphs imitating Latin, or hides invisible / text-direction characters. Genuine monolingual text passes, including accented French. This guards the registered-name namespace against impersonation, which a message-content filter on the ircd never sees.

It's on by default and can be turned off per network — see [`[register]`](Configuration#register).
