# TLDR
fix bug due to some event properties coming from the google calendar API
containing weird characters like this
"\u0000�4\u000b\u00042��K\u0001�z,\u001cm�",
it made the Postgres select and insert operator fail
## Details
We can have event properties (like cal UID below) encoded in a strange
way. From my research, the character \u0000 comes from `C` language to
signal end of line. It is wrongly interpreted by Postgres so must be
escaped. I decided to remove all possibility of failure with this regex
`[^\x20-\x7E]` basically "any character that is not a printable ASCII
character"
