Post-processing fails if sentence has <number><space><number>

[iamanigeeit]

Problem
The parser will output a non-breaking space character if the the input sentence contains \d+ \d+. This leads post-processing failure with error penman.DecodeError: Expected ":" or "/" at position XXX

Example .pred file

# ::id 9900
# ::snt @united iCloud it's not there yet -- PLEASE HELP 917 703 1472
# ::tokens ["@united", "iCloud", "it", "'s", "not", "there", "yet", "--", "PLEASE", "HELP", "917\u00a0703\u00a01472"]
# ::lemmas ["@united", "icloud", "it", "be", "not", "there", "yet", "--", "please", "help", "917\u00a0703\u00a01472"]
# ::pos_tags ["VBN", "NN", "PRP", "VBZ", "RB", "RB", "RB", ":", "VB", "NN", "CD"]
# ::ner_tags ["O", "O", "O", "O", "O", "O", "O", "O", "O", "O", "NUMBER"]
# ::abstract_map {}
(c0 / multi-sentence
    :snt1 (c1 / icloud
              :mod (c3 / be-located-at
                       :ARG1 (c7 / it)
                       :ARG2 (c8 / there)
                       :time (c9 / yet)))
    :snt2 (c2 / help-01
              :ARG1 (c4 / you)
              :mode imperative
              :ARG1 (c6 / book
                        :name (c10 / 917 703 1472))))

Note that in the last line, 917 703 1472 contains non-breaking spaces.

penman.DecodeError: Expected ":" or "/" at position 364

Workaround
Check for non-breaking spaces and replace them with - or _ in the output.

While this repo uses an old version of penman, this issue also affects the latest version. I've created goodmami/penman#99 to track the issue there.
