Issue with unicode_utils gem

[n-rodriguez]

Hi there!

strings depends on unicode_utils (https://github.com/piotrmurach/strings/blob/master/strings.gemspec#L27)

unicode_utils is not compatible with frozen_string_literal https://github.com/lang/unicode_utils/issues/13 and don't seem to be maintained 😢

And so it breaks with :

/Users/nicolas/PROJECTS/CONCERTO/concerto/.bundle/ruby/3.3.0/gems/unicode_utils-1.4.0/lib/unicode_utils/read_cdata.rb:124:in `force_encoding': can't modify frozen String: "x", created at /Users/nicolas/PROJECTS/CONCERTO/concerto/.bundle/ruby/3.3.0/gems/unicode_utils-1.4.0/lib/unicode_utils/read_cdata.rb:123 (FrozenError)

Because I've enabled frozen-string-literal globally in my Rails project :

export RUBYOPT="--enable=frozen-string-literal --debug=frozen-string-literal"

See: https://gist.github.com/fxn/bf4eed2505c76f4fca03ab48c43adc72

A solution would be to vendor/include what you need from unicode_utils :

https://github.com/piotrmurach/strings/blob/master/lib/strings/truncate.rb#L5 https://github.com/piotrmurach/strings/blob/master/lib/strings/wrap.rb#L5

https://github.com/lang/unicode_utils/blob/master/lib/unicode_utils/each_grapheme.rb https://github.com/lang/unicode_utils/blob/master/lib/unicode_utils/read_cdata.rb

Thank you!
