Answer 1

I think you can also change the regexps from the syntax /re/ to the syntax (Regexp.new 're', nil, 'n')

For example, the instruction you mentioned:

string.gsub! /á|ã|à|ä|â/, 'a'

will become:

string.gsub! (Regexp.new 'á|ã|à|ä|â', nil, 'n'), 'a'

Answer 2

Write # encoding: utf-8 on top of that file. That changes the default encoding of all string/regexp literals in that file utf-8. The default encoding for all literals is US-ASCII, which cannot represent á.

Answer 3

To make it project-wide, try: the magic_encoding gem.
