Wolfgang, have you retested this issue with Lighting 0.9? Does it work now?

Comment 3

[Martin Schröder [:mschroeder]]

Nuno, Wolfgang: ENCODING=QUOTED_PRINTABLE is not part of the iCalendar standard (see http://tools.ietf.org/html/draft-ietf-calsify-rfc2445bis-09#section-3.2.7). So this is more an enhancement request than a bug.

Comment 4

Hi Martin,


As you can see, the provided sample is not specifically compliant to iCalendar but is a VCalendar: http://www.imc.org/pdi/vcal-10.txt, where the quoted-printable encoding is permitted.

Moreover and more generally, even if the standard doesn't not specify it, it doesn't mean Lightning cannot be tolerant.

vCalendar 1.0 has many differences from iCalendar 2.0

The extension vcsSupport
https://addons.mozilla.org/en-US/sunbird/addon/4721
provides some support for vCalendar, though I don't know if the latest version accepts this particular file (a comment suggests a previous version does not).  I think you may be more likely to get a fix there.
