Fix emoji support in comments and project descriptions

[moio]

Emojis (e.g., 😱) in comments or project descriptions cause HTTP 500. MySQL's utf8 charset only supports 3-byte UTF-8; emojis require 4-byte utf8mb4.

Fixes #585.

This was made with Copilot agents as part of experiments for my HackWeek project.

I tested it manually and it works in my environment, as far as I can tell:

docker-compose exec hackweek bundle exec rspec apparently fails mid way for reasons I don’t understand. In logs I see:

hackweek-hackweek-1  | 15:13:49 system   | sending SIGTERM to all processes                                            │All examples were filtered out; ignoring {focus: true}

I hope this helps. Feedback welcome.

Hey, thanks for contributing!

Is your docker compose up? Try with docker compose run hackweek bundle exec rspec instead. Remember exec only works for containers that are running...

Also, you need to run the migrations locally and upload the modified schema file

thanks @danidoni

So first of all I am trying to run rspec tests on clean master, without the changes here.

App is up, but I see my emoji projects, so resetting the database.

IIUC the right command is

docker compose run hackweek bundle exec rake db:drop db:create db:migrate

This fails with:

-- add_attachment(:projects, :avatar)
rake aborted!
StandardError: An error has occurred, all later migrations canceled: (StandardError)

/hackweek/db/migrate/20140910105916_add_avatar_columns_to_projects.rb:3:in 'AddAvatarColumnsToProjects.up'

Caused by:

Did you mean?  add_column
/hackweek/vendor/bundle/ruby/3.4.0/gems/activerecord-7.2.3/lib/active_record/migration.rb:1058:in 'block in ActiveRecord::Migration#method_missing'

What am I doing wrong?

I would check out master and run `docker-compose run --rm hackweek bundle exec rake dev:bootstrap` to start clean, as documented here: https://github.com/SUSE/hackweek?tab=readme-ov-file#hack-it

[moio]

Right, thanks.

Checking out from master branch, then running docker-compose run --rm hackweek bundle exec rake dev:bootstrap, then running docker-compose up --build and finally docker compose run hackweek bundle exec rspec from another console results in:

Checking out this branch, re-running docker-compose run --rm hackweek bundle exec rake dev:bootstrap and then docker-compose up --build, and finally docker compose run hackweek bundle exec rspec in a different console leads me to the exact same 16 failures (the 3 added examples in this PR pass).

Is it safe to assume the problem lies elsewhere?

Is there anything else I should do for this PR to be mergeable?

I don't know what to tell you... I started from a fresh start, on master, and I don't have any error... Did you try removing all containers from that project and rebuild again from scratch?
