Resolve glyph error

[s2t2]

When parsing page 728 of the Salt Lake City District Court .pdf file, the script is encountering an error Unknown glyph width for 127 Courier:

/usr/local/var/rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/pdf-reader-1.3.3/lib/pdf/reader/width_calculator/built_in.rb:93:in `glyph_width': Unknown glyph width for 127 Courier (ArgumentError) 

[s2t2]

the gem author says this issue has been resolved on the master branch, but using the gem from github source does not resolve the issue.

# Gemfile
gem 'pdf-reader', :git => 'git://github.com/yob/pdf-reader.git'

[s2t2]

see screenshot below.

the offending character is ØN§ûø•

edit: the offending character appears again on page 819

edit: the Payson City Justice Court calendar also triggers this error on page 47, although the offending character is unclear.
