need documentation on installing and using cpimport in 1.4+

Need help getting correct install repo and if it can be installed remotely like mcsimport was able to in a 1.4+ documentation.

The LOAD DATA LOCAL INFILE web page has a note about using cpimport for data that has multi-byte characters. I'm going on the assumption that mcsimport can also be used with multi-byte characters.

We are having issues getting the api SDK installed. The docs are confusing and its unclear what repository to use. Using the one on the web page did not work.
We are using :
[MariaDB]
baseurl = https://yum.mariadb.org/10.4/centos7-amd64
gpgcheck = 1
gpgkey = https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
name = MariaDB 10.4 CentOS repository
repo_gpgcheck = 1

and installing the package is not working:
sudo yum install mariadb-columnstore-api*

So, no mcsimport command is available yet.
That is the same repository we are getting the client software to install on remote machines.

However, I noticed the note that said
MariaDB ColumnStore API (Bulk Write SDK) Package<https://mariadb.com/kb/en/installing-mariadb-ax-mariadb-columnstore-from-the-package-repositories-12x/#mariadb-columnstore-api-bulk-write-sdk-package>
Is deprecated as of version 1.4. I take it that means mcsimport is being deprecated.

So if mcsimport is being discontinued, then I must use cpimport.
One of the points we are trying to accomplish is to load data from a remote node, not to run cpimports on a cluster node.
If LOAD DATA LOCAL INFILE can not handle multi-byte characters it sounds like we need a different solution that will work from a remote node.
