Are UK entry bans reported in Europe? (Flying from UK to Europe).

[jk199490]

Me and my fiancé who has overstayed her visitor visa in the UK are planning on going to Europe then onwards to Brazil.

However, at exit I'll assume she'll automatically be applied with a 12 months ban as she overstayed her UK visitor visa by a considerable amount of time.

If she does have an entry ban, will this prevent her from entering Europe? (note: she doesn't need to apply for a visa before we go, Brazilian citizens can go for 90 days without a prior visa).

I'm aware that the UK has limited access to SIS (or at least they did before Brexit) but I'm not sure of the exact reporting powers they have with the rest of Europe.
