# encoding:utf-8

"á is the first letter" =~ /^(.)(.*)/u

puts "-->#{$1}<--"
puts "-->#{$2}<--"

--output:--
-->á<--
--> is the first letter<--

"â is the first letter" =~ /^(.)(.*)/u

conversion_hash = {
   'â' => 'a',
   'ê' => 'e',
   'ơ' => 'o',
   'í' => 'i',
   'ũ' => 'u'
}

puts "#{conversion_hash[$1]}#{$2}"

--output:--
a is the first letter
