| | UTR# 36: Unicode Security Considerations |
 | | Spoofing is not dependent on just homographs; if the visual appearance is close enough at small sizes or in the most common fonts, that can be sufficient to cause problems. |
 | | Because of the widespread commercial use of English and other Latin-based languages (such as "خدمة RSS"), it is quite common to have instances of Latin (especially ASCII) in text that principally consists of other scripts. |
 | | For examples, consider proper names such as "Zoë", words from the Oxford English Dictionary such as "coöperate", and many foreign words, proper or not, that are in common use: "René", ‘naïve’, ‘déjà vu’, ‘résumé’, etc… Thus the problem with restricting identifiers by language is the difficulty in defining exactly what that implies. |
