Fix emojis in a different way

Apparently the existing fix is difficult to ship for distros. This is an alternative way, that manually goes over every text and sets the font family appropriately.
Unfortunately, we need a textDocument for that, which labels don't have, meaning we have to use TextEdits instead...

+## Introduction
+
+NeoChat is a client for [Matrix](https://matrix.org), the decentralized communication protocol for instant
+messaging. It is a fork of Spectral, using KDE frameworks, most notably [Kirigami](https://invent.kde.org/frameworks/kirigami)
+to provide a convergent experience across multiple platforms.
+
+NeoChat also make use of other KDE Frameworks as well as [libQuotient](https://github.com/quotient-im/libQuotient), a
+Qt-based SDK for the [Matrix Protocol](https://spec.matrix.org/).
+
+![Timeline](https://cdn.kde.org/screenshots/neochat/application.png)
+
+## Features
+
+NeoChat aims to be a fully featured application for the Matrix specification. As such everything in the current stable specification with the notable exceptions
+of VoIP, threads and some aspects of End-to-End Encryption are supported. There are a few other smaller omissions due to the fact that the Matrix spec is constantly
+evolving but the aim remains to provide eventual support for the entire spec.
+
+Due to the nature of the Matrix specification development NeoChat also supports numerous unstable features. Currently these are:
+- Polls - MSC3381
+- Sticker Packs - MSC2545
+- Location Events - MSC3488
 
 ## Get it
 
-A stable release [is available](https://apps.kde.org/neochat) for download for Linux distributions.
+Details where to find stable releases for NeoChat can be found on its [homepage](https://apps.kde.org/neochat).
 
+In addition to the stable builds, unstable nightly builds are available for all platforms. These can be downloaded
+from the [binary factory](https://binary-factory.kde.org/). There are unstable versions for the following platforms
+in addition to stable ones:
+- Android
+- MacOS
+- Windows
 
-Along with the stable release, a Flatpak version is available for the nightly
-version:
+Additionally the nightly Flatpak version can be obtained from the nightly Flatpak repo using the following commands in your terminal:
 
 ```
 flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
@@ -26,42 +53,53 @@ flatpak remote-add --if-not-exists kdeapps --from https://distribute.kde.org/kde

 ```
 
-A nightly build is also available for Android in the [KDE nightly F-Droid repo](https://community.kde.org/Android/FDroid)
-and can also directly be downloaded from the [binary factory](https://binary-factory.kde.org/view/Android/job/NeoChat_Nightly_android-arm64/).
+The unstable Android version can also be obtained from the [KDE nightly F-Droid repo](https://community.kde.org/Android/FDroid).
 
-Nightly builds for [Windows](https://binary-factory.kde.org/job/NeoChat_Nightly_win64/), [MacOS](https://binary-factory.kde.org/job/NeoChat_Nightly_macos/) and [AppImages](https://binary-factory.kde.org/job/NeoChat_Nightly_appimage/) can also be downloaded from the [binary factory](https://binary-factory.kde.org/search/?q=neochat).
+## Running
 
-![Timeline](https://cdn.kde.org/screenshots/neochat/application.png)
+Just start the executable in your preferred way - either from the build directory or from the installed location.
 
-## Features
+## Building NeoChat
 
-* Sending messages
-* Sending files from clipboard and filesystem
-* Reply to message (right-click on a message to access menu)
-* Start a private chat (but not encrypted)
-* Show notifications, for the moment there is only a global switch
-to disable it. We plan to implement the configuration part of the
-specification soon.
-* Autocompletion of usernames in chat
-* Emoji picker
-* Basic room setting page
-* Send and accept invitations
-* /rainbow <message> (very important)
-* /me <message>
+The best way to build KDE apps during development is to use `kdesrc-build`. The full instructions for this can be found on
+the KDE community website's get involved section under [development](https://community.kde.org/Get_Involved/development). This
+is primarily aimed at Linux development.
 
-NeoChat is still missing a few features to become a full-featured
-Matrix client (most notably encryption support and video chat support).
-We welcome contributions in this direction.
+For Windows and Android [Craft](https://invent.kde.org/packaging/craft) is the primary choice. There are guides for setting up
+development environments for [Windows](https://community.kde.org/Get_Involved/development/Windows) and [Android](https://develop.kde.org/docs/packaging/android/building_applications/).
+
+## Tests
+
+Tests are in the repository under [autotests](autotests) and should all pass for any contribution.
+
+The project has CI setup to test new commits to the repository. All tests are expected to pass for a merge request to
+be complete.
+
+Current build status
+
+![coverage](https://invent.kde.org/network/neochat/badges/master/pipeline.svg)
+
+Currently the number of tests is limited, but growing. If anyone wants to help improve this, those
+contributions would be especially welcome.
+
+## Contributing
+
+As is the case throughout the KDE ecosystem contributions are welcome from all. The code base is managed in the
+[NeoChat repository](https://invent.kde.org/network/neochat) of the KDE Gitlab instance.
