Node#visible_text use scrub to replace invalid UTF-8 sequences

[reedrolemodel]

Some pages cause a invalid byte sequence in UTF-8 exception to be raised when calling text.to_s.gsub(/\A[[:space:]&&[^\u00a0]]+/, ''). Adding scrub prevents this.

Specific context:
It seems a   HTML entity gets interpreted as "\xA0", or byte 160, which has an invalid encoding. Using charlock_homes the encoding of the entire page is reported as ISO-8859-1 with 54% confidence.

I came here to report the issue! I'm glad to discover it already has a PR.

  1) Static pages GET /de/cookies renders a cookie policy
     Failure/Error:
       text.to_s.gsub(/\A[[:space:]&&[^\u00a0]]+/, '')
           .gsub(/[[:space:]&&[^\u00a0]]+\z/, '')
           .gsub(/\n+/, "\n")
           .tr("\u00a0", ' ')

     ArgumentError:
       invalid byte sequence in UTF-8
