You can go through a series of steps:</p> <pre><code>// original string NSString *str = @"ÁlgeBra"; // convert to a data object, using a lossy conversion to ASCII NSData *asciiEncoded = [str dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; // take the data object and recreate a string using the lossy conversion NSString *other = [[NSString alloc] initWithData:asciiEncoded encoding:NSASCIIStringEncoding]; // relinquish ownership [other autorelease]; // create final capitalized string NSString *final = [other capitalizedString]; </code></pre> <p>The documentation for <a href="http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html"><code>dataUsingEncoding:allowLossyConversion:</code></a> explicitly says that the letter ‘Á’ will convert to ‘A’ when converting to ASCII.</p>
