Subject: Re: How can i get the first letter of this string

thanks for all!
I tried all instructions above and they work fine when i run from 
command line. But when i insert them to my .rb file in my project and 
debug, An error has happen, and i don't know why

"á is the first letter" =~ /^(.)(.*)/u
puts "-->#{$1}<--"
puts "-->#{$2}<--"

--output in command prompt window:--
-->á<--
--> is the first letter<--

But in the log file of my project
I 03/04/2011 09:07:39:169 b0353000  APP| -->√<--
I 03/04/2011 09:07:39:169 b0353000  APP| -->° is the first letter<--

Again, i change the code:

"á is the first letter" =~ /^(..)(.*)/u
puts "-->#{$1}<--"
puts "-->#{$2}<--"

And now it works.
I 03/04/2011 09:11:03:414 b03d5000   APP| -->á<--
I 03/04/2011 09:11:03:414 b03d5000   APP| --> is the first letter<--

My project is a rhodes project. Rhodes version 2.2.6. Ruby 1.8.7.
