@9iks Thank you for the PR.

It appears that CI is failing due to an issue with generating mnemonics. I think a duplicate word is being generated and failing the test but I have not ran it up to debug.

Are you able to investigate this test?

Sorry, English is not my native language.
My OS :Mac 10.13.6
The complete project failed to compile because of the ~/bip39/make_dictionary/main.cpp file, line 18 references "experimental/filesystem".
I generate the bip39.xcodeproj file by executing the command "make -GXcode." in the ~/bip39/ src directory, and finally use xcode to compile the libbip39.a
In this source code, I simply appended "rbe.seed(std::random_device()());" to line 123 of the ~/bip39/src/bip39.cpp file.
