  o You can: require "unicode/display_width/string_ext" to continue to use
    the string extension

Log message:
textproc/ruby-unicode-display_width: import ruby26-unicode-display_width-1.6.0

Determines the monospace display width of a string in Ruby.
Implementation based on EastAsianWidth.txt and other data, 100% in
Ruby. Other than wcwidth(), which fulfills a similar purpose, it
does not rely on the OS vendor to provide an up-to-date method for
measuring string width.
