Sanitize the calendar data coming from Gadgetbridge?

Hello,

I am using the Rebble Agenda app and I noticed some weird artefacts (see attachment, event name redacted for privacy).

After further investigation, I saw that the artefacts actually come from the android.calendar.json file provided from Gadgetbridge.

Here is an example of an event with such artefacts:

{t:"calendar",id:85,type:0,timestamp:1711371600,durationInSeconds:3600,title:"redacted",description:"-::~:~::~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~::~:~::-\nParticiper via Google\xA0Meet\xA0: https://meet.google.com/redacted\nOu composez le\xA0: (FR) redacted Cod...",location:"",calName:"redacted",color:-6299161,allDay:false}

It looks like events that come from Google Workspace with a Google Meet invitation include some weird -::~:~::~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~:~::~:~::- separators that completely mess up the UI.

Another event is difficult to read because it has HTML tags in it:

description:"<html-blob><u></u><u></u><u></u><p><b>redacted &nbsp;</b>redacted</p><p><b><br></b></p><p><u><b>redacted&...

Would it be possible to "sanitize" this data coming from Gadgetbridge, maybe using a regex to remove HTML tags and separators?

It would subsequently fix all the apps that require the JSON file.

Thanks
