bug#33418: Convert from literal string to ERE? |

Hi,
I'd like to create an ERE expression for any literal string. I found
that "sed -e 's/\([][?+{|()\]\)/\\\1/g' " seem to work.
For example,
sed -e 's/\([][?+{|()\]\)/\\\1/g' <<< '\?+{|()[]'
Could anybody help confirm whether this will work for all the cases? Thanks.
