Map file no match when key contains space - escaping not working

I’m trying to use a map file to make dynamic backend decisions based on user agent strings.
Problem is my user agent has spaces in it.
The mapfile works without spaces:

teststring dest_pool

and in the cfg:
acl has_http_useragent hdr(user-agent),map_str(/usr/local/haproxy/maps/webcenter_useragents.cfg) -m found
use_backend %[req.hdr(user-agent),map_str(/usr/local/haproxy/maps/webcenter_useragents.cfg)] if has_http_useragent

If I add and escape a space it doesn’t match anymore:

test\ string dest_pool

I get a NOSRV

Q1. Can I change the default delimiter for the k/v’s in a map ? I have not found a reference to that.
Q2. Is there any other way to deal with the spaces ?

Unfortunately, my user agent is “Studio Site Designer”

Thx for a great product
