SQLi information_schema in mysql (WAF)

Hi, guys. How to bypass "information_schema" word filtration? Random upcase, urlencoding, etc... not working. I think this is a nginx filtration.

Hi. This is a post request. Nginx blocking any*information_schema*any.

information_sch\u0065ma - blocked
information_sch\u00f0ma - not blocked, but not working.

UPD. Not any*information_schema*any - information_schema pattern. Sorry for poor english. Innodb method not working, performance_schema not found.

I can't share link, for security reason. White hat pentest. If you can help me, show me how to obfuscate 'information_schema' pattern.
