[BUG] Serialize does not use CRLF sequence

[GustavoOS]

Current Behavior:

• Generates string unix style (LF endings)

Expected Behavior:

• CRLF endings, following RFC 5545.3.1

Steps To Reproduce:

1. Create a calendar
2. Call calendar.Serialize()

Anything else:

RFC 5545.3.1 states that lines should be delimited by CRLF sequence

[GustavoOS]

It turns out that this is simply a bad default.
A workaround for this is to set explicit endings on serialize:

calendar.Serialize(ics.WithNewLineWindows)

Hey,

That was a recent change too. I will look into it, but it might have to be a documentation improvement for the mean time. (I mean there is a massive scope for improvement there already!)
