The UTF8 support did not make it into release 2.14, but it (in my opinion) essentially ready for production use. I expect to have a production server running it in about a week, and several other people have already been using various versions of the code with UTF8 support in production elsewhere for well over a year.
If you are comfortable using git to update webwork2 and pg, you should be able to get the UTF8 code working on your current server using the code from the 2 pull requests covered below.
However, it almost certainly makes sense to try out the UTF8 support first in Docker first. That approach is safer than hacking on your main server. See:

If you have a pg directory which has the Git data, the following should hopefully get what you need installed:
cd PATH/pg # Fix the path...
git remote add mgage https://github.com/mgage/pg.git
# Next command is one long line
git checkout -b new_develop_candidate_multilingual remotes/mgage/new_develop_candidate_multilingual
# Should show that you are on the new_develop_candidate_multilingual branch...
webwork2:
https://github.com/openwebwork/webwork2/pull/927 which I think is almost "good enough" (but will have some database related issues if you use the utfmb4 charset, a "full" SQL utf8 which supports also 4 byte characters, for the database tables as is recommended for storing "real" utf8 data) or a slightly updated version with some recent changes I submitted to fix those issues when utf8mb4 is used by the database backend. Hopefully my changes will be merged into the main PR 927 soon.
If you have a webwork2 directory which has the Git data, the following should hopefully get what you need installed (I'm recommending using mgage's branch which "feeds" into the main PR 927
cd PATH/webwork2 # Fix the path...
git remote add mgage https://github.com/mgage/webwork2.git
git fetch mgage
# Next command is one long line
git checkout -b develop_candidate_02_24_2019 remotes/mgage/develop_candidate_02_24_2019
git status
# Should show that you are on the develop_candidate_02_24_2019 branch...
# The next steps would pull in my recent changes, if desired
git fetch mgage pull/24/head:develop_candidate_02_24_2019_utf8mb4
git checkout develop_candidate_02_24_2019_utf8mb4
