I would say it is similar to ~~bug #7031~~ but not a duplicate. Parsing colons is okay (probably as that bug got fixed) but the parsing problem reported here is about semicolons.

The parsing part sounds like a duplicate of ~~bug #7031~~.

Currently iCalendar.php fails to deal with parameter values which contain a ";" when importing data. As per RFC 2445 certain parameter values need to be quoted. Quoted parameters values are not recognized by iCalendar.php. When exporting data the parameters may not contain all possible characters (e.g. control characters would be invalid). In addition parameter values that contain a ";", ":", or "," need to be quoted. Another problem are two byte UTF-8 characters in parameter values: As far as I can tell RFC 2445 allows these in an unquoted form. Nevertheless Outlook seems to be unable to deal which unquoted parameter values when they contain such characters. See also https://www.intevation.de/roundup/kolab/issue3284 Our suggested solution is to also quote parameter values once there are two-byte characters in the string. Suggested patch attached.
