I18n Issues

Use of an explicit (non-Unicode) encoding may cause problems when later moving to a multilingual environment.

Resolution: Adopt UTF-8 or UTF-16 as the encoding.

Note: This method stores the specified encoding with the file in an extended attribute under the name com.apple.TextEncoding. The value contains the IANA name for the encoding and the CFStringEncoding value for the encoding, separated by a semicolon. The methods initWithContentsOfFile:usedEncoding:error:, initWithContentsOfURL:usedEncoding:error:, stringWithContentsOfFile:usedEncoding:error:, and stringWithContentsOfURL:usedEncoding:error: use this information to open the file using the right encoding.

Generally one needs to pass in locale, encoding or language to ensure that any culture-dependent conversion is done properly. If you determine that the call is i18n-safe, you can use Globalyzer's Ignore Comment functionality to ensure that it isn't picked up in a subsequent scan.
