The Rails Active Support gem provides upcase, downcase, swapcase,capitalize, etc. methods with internationalization support:

> gem install activesupport  
> irb -ractive\_support/core\_ext/string  
> “STRING ÁÂÃÀÇÉÊÍÓÔÕÚ”.mb\_chars.downcase.to\_s  
> =\> “string áâãàçéêíóôõú”  
> “string áâãàçéêíóôõú”.mb\_chars.upcase.to\_s  
> =\> “STRING ÁÂÃÀÇÉÊÍÓÔÕÚ”

[source](http://stackoverflow.com/questions/1020568/how-to-convert-a-string-to-lower-or-upper-case-in-ruby)

Performance wise: 10000000 iterations in C#

ToLower(): 1054 ms  
ToLowerInvariant(): 1724 ms  
ToLower(CultureInfo): 884 ms [fastest]

Don’t think it’s an issue.
