note 110543 deleted from function.mb-detect-encoding by aharvey

Note Submitter: geoff at spacevs dot com ---- Users, please note that @Mahn is also wrong... "The detected character encoding or FALSE if the encoding cannot be detected from the given string." @ikatalog at web dot de's first function is correct, his 2nd one is not, it should be checking for '!== false', which is faster then a string comparison of 'UTF-8' as @Mahn suggested.
