v2.3.11.3 solr plugin search via MUA fails to match accented ascii characters; cmd line exec of `doveadm fts lookup` PANICs (assertion failed)

[PGNet Dev]

exec'ing search from Roundcube client, instead of TBird, accented-text search WORKS in both cases,

"subject = aausdfrhyétdwgyatrdf" only,

note the apparent folded search for _all_ of

	aausdfrhyétdwgyatrdf
	aausdfrhyètdwgyatrdf
	aausdfrhyetdwgyatrdf

this^ is with normalization-icu _out_ of the loop, due to the apparent missing libicu lib links in pkg build
