Description

  1. echo á | grep '[[=a=]]'
  2. echo ô | grep '[[=o=]]' #

On Linux to compare:

  1. echo á | grep '[[=a=]]'
    á
  2. echo ô | grep '[[=o=]]'
    ô #

Hello,
Do you know if this only occurs with OI or with other illumos-based distributions ?
Kind regards

Some documentation at GNU grep mentioned that the support was initially for glibc-based systems only.
Please check upstream if this is a bug specific to OI or a known limitation of GNU grep.
