Issue parsing ics from Beeline, Inc

[lloiodice]

We run into an ICS which has the following line:

SUMMARY; ENCODING=QUOTED-PRINTABLE:Interview:=20Kalim,=20Usraa=20(24524-1)

iCal.Net library version 4.1.11 throws an exception:
Could not parse line: 'SUMMARY; ENCODING=QUOTED-PRINTABLE:Interview:=20Kalim,=20Usraa=20(24524-1)'

Would you know why this is not supported?

Thanks in advance

I have the same issue

I have a similar issue with fields with QUOTED-PRINTABLE Encoding.

I can see that problems with parsing of are already associated with test data /src/Ical.Net.CoreUnitTests/Calendars/Serialization/Parse1.ics.

The associated unit test asserts that the result is either a not null or a SerializationException.

However the field I have in source data look more like this which isn't even real QUOTED-PRINTABLE:

And I am expecting the description field to contain something like:
