> In the docker-based tests on Redhat 8 / Ubuntu 20, the ExprTest.Utf8MaskTest fails:
> {noformat}
> /home/impdev/Impala/be/src/exprs/expr-test.cc:369
> Value of: GetValue(expr, ColumnType(TYPE_STRING))
>   Actual: "xxxx \xC3\xA1\xC3\xA4\xC3\xA8\xC3\xBC XXXX \xC3\x81\xC3\x84\xC3\x88\xC3\x9C"
> Expected: expected_result
> Which is: "xxxx xxxx XXXX XXXX"
> mask('abcd  ABCD '){noformat}
> These come with the C.UTF-8 locale installed. This error goes away if I change bin/bootstrap_system.sh to install langpacks-us (Centos) or language-pack-en (Ubuntu), which installs the en_US.UTF-8 locale.
> This might be related to this code: [https://github.com/apache/impala/blob/master/be/src/exprs/mask-functions-ir.cc#L150]
> Installing the language packs is easy, but I'm not sure if users would have those installed.
