Hello Mnn,
Welcome to Microsoft Q&A forum.
I understand how inconvenience it could be when a daily use symbol is not available on the specific keyboard for the language, so thank you for the suggestion.
As helpful as the suggestion could be, this might not be the correct page to submit it. This is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas. In this case, Microsoft does provide users with a channel so they can directly submit their ideas or suggestions with the Windows engineering team, which is the Feedback Hub apps. This is available by default on every Windows computer; you can go and submit your ideas there so they can know about it and decide to implement the idea on a future update. Thank you for your understanding.
