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.

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.
