Converting to properties (t/map->properties) fails with Mac environmental variables

[evmin]

(def config (load-config :resource "config.edn"
                         :merge [(from-env)]))

(defn config-properties []
        (t/map->properties config))

Results in:

Exception in thread "main" java.lang.IllegalArgumentException: Malformed \uxxxx encoding., compiling:(/private/var/folders/hl/dz69nmk50kl_cn4fgd904dwh0000gn/T/form-init5308382940781279132.clj:1:125)

If "(from-env)" is removed, everything works. I suspect that parsing of one of the env variables might be causing this. I'm on Mac.

I am attaching a code sample to reproduce.

The output included as result.txt is from the first call that works: semi - custom logic, based on other private methods in the lib to convert config to Properties.
