That explained part of an issue I had where I tried adding events to a calendar with a space inside of the name of the calendar.
I have three calendars that start with the letter f, and the third contained both a special character (æ) and a space in the name. Are there any way to get events into this calendar at all? If only the search would allow for the special character æ to be found so the space might be ignored that might work since the word with æ is the first word so the match might be possible to make without allowing spaces when looking for the right calendar.
