Fails when DESCRIPTION field has newlines

[io12]

When the DESCRIPTION field of an ical has line breaks (not \n escapes, but actual newline characters), this tool discards the rest of the description. To reproduce this, take any ical file with a description and insert a line break in the description.

[msherry]

Is it valid to allow literal newlines, rather than \n characters? I'm looking at https://tools.ietf.org/html/rfc5545#section-3.3.11, and TSAFE-CHAR seems to skip over 0x0A and 0x0D, which represent \n and \r, respectively.

[io12]

The ics npm package inserts literal newlines to break up long lines. Based on the usage, it seems like they're supposed to be ignored, not treated as a newline inside the description.

Example to reproduce

const ics = require('ics')

const event = {
    start: [2018, 5, 30, 6, 30],
    duration: { hours: 6, minutes: 30 },
    title: 'Bolder Boulder',
    description: 'Annual 10-kilometer run in Boulder, ColoradoAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAÁ',
    location: 'Folsom Field, University of Colorado (finish line)',
    url: 'http://www.bolderboulder.com/',
    geo: { lat: 40.0095, lon: 105.2669 },
    categories: ['10k races', 'Memorial Day Weekend', 'Boulder CO'],
    status: 'CONFIRMED',
    busyStatus: 'BUSY',
    organizer: { name: 'Admin', email: 'Race@BolderBOULDER.com' },
    attendees: [
        { name: 'Adam Gibbons', email: 'adam@example.com', rsvp: true, partstat: 'ACCEPTED', role: 'REQ-PARTICIPANT' },
        { name: 'Brittany Seaton', email: 'brittany@example2.org', dir: 'https://linkedin.com/in/brittanyseaton', role: 'OPT-PARTICIPANT' }
    ]
}

ics.createEvent(event, (error, value) => {
    if (error) {
        console.log(error)
        return
    }

    console.log(value)
})
