UnicodeDecodeError when installation

[Prinway]

I'm using Python 3.7.0 with the latest pip (23.1.1). An UnicodeDecodeError occurs when installing RSOME 1.1.4.

Installing build dependencies ... done Getting requirements to build wheel ... error

Here are the traceback outputs:

My OS is Windows with the language of Chinese. For some reason, Python would try to decode the file content as gbk. As hinted in the above output, there must be some characters that cannot be decoded by gbk. I download the source code of RSOME and tried to debug locally and find the troublemaking character –.

More specifically, it is the character between the two number of pages 3329 and 3339 in the citation of your great paper in the README.md.

I replaced the – to - and repackaged the project. After that, the installation is fully successful! Users who are using ASCII incompatible encodings would appreciate if you can fix this in the new versions. Thank you!

Hi @Prinway thank you for reporting this issue. We have changed the hyphen sign in the README file for version 1.2.0. Hopefully, this installation issue is fixed.
