    Unicode is important here because a QString can contain characters from different writing systems, and converting it to QByteArray without specifying the correct encoding can result in data loss. Using UTF-8 is generally a practical choice when the data needs to preserve Unicode characters across different applications and systems. This is especially important for multilingual text such as Arabic and Urdu, where proper Unicode support is essential for preserving the characters correctly.

    I filed this issue too: https://qt-project.atlassian.net/browse/QTBUG-150742 - a suggestion to add support for unix sockets in the SatelliteSource object, which would mean no need to pipe gnss-share output. I would really like for someone to confirm if the sattlitesInView list is empty - I have not been able to fix that, and I consider filing an issue for that as well.

    Hi, I can only answer on the last part: Qt6 Multimedia module currently uses ffmpeg as backend on all platform except for embedded Linux which might be your case. I suggest you take a look at GStreamer chapter in the Qt Multimedia documentation. There might be stuff in there that could be of interest. Hope it helps

    Hi and welcome to devnet, Sounds like you have encountered the same situation as described in QTCREATORBUG-34905 which is fixed for 20.0.2. If you want you can use the snapshot. @ekkescorner confirmed it works.

    Change node.material = material; to node.materials = [material]; because the Model in QtQuick3D has a property called materials (a list), not a single material.

    For an educational project, I want to compile Qt 6 C# (presumably, via the new Qt Bridge) to GitLab Pages-compatible WASM (presumably, via Emscripten). Is this feasible, and/or possible? If not, I am happy to file an enhancement request for Qt Jira's QTBRIDGES product. Though, I fear that it may be as difficult as what github.com/pyodide/pyodide-recipes/issues/183 describes.

    Try an unoptimized build first (without optimizations) to verify a code folding/LTO issue, and if so, update emsdk to a newer version; if you don't feel like messing with it, moving the file is the quick fix.

    I am working on a Qt for MCUs application and currently using OTF font files with the Static font engine. The font quality is good with OTF, but internal flash usage becomes very high. When I use FMP fonts, flash usage is low, but some glyphs do not render properly. Any guidance on the correct approach to move OTF font storage to external memory would be very helpful. Thank you.
