brew doctor 時にwarninngが出てきます。

Question

idr 時に日本語の文字化けを治したいのですが、いろいろな方法を試したのですが、いまだに治りません。
下記のwarningはなにかしら関係があるでしょうか?

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
./configure scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
/Library/Frameworks/Python.framework/Versions/3.8/bin/python3-config
/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8-config

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected dylibs:
/usr/local/lib/librtmp.dylib
