Are you absolutely certain that your file is UTF-8 encoded?

$ cat i.rb
#Encoding: UTF-8
verb = "appèler"
puts "The verb was #{verb}" if verb =~ /èler/

$ ruby -v i.rb
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]
The verb was appèler

$ enca -L none i.rb
Universal transformation format 8 bits; UTF-8

$ iconv -t LATIN1 -f UTF8 < i.rb > l.rb

$ enca -L none l.rb
Unrecognized encoding

$ ruby -v l.rb
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]
l.rb:2: invalid multibyte char (UTF-8)
l.rb:2: syntax error, unexpected tIDENTIFIER, expecting $end
verb = "app?ler"
