Thank you for your question and Wiki status is changed. > You state "Mapping with other character codes may be incompatible", for one of the > reasons not to support this. > Can you please explain this a bit more? Sure. For example, Japanese character code, If try to match hiragana for each character code, it will end up with different bytes. Hiragana letter matches in UTF-8. [ぁ-ゞ] But other character code is sometimes different. example: EUC-JP [ぁ-ん゛ゝゞ] Sometimes the order is different why I say "Mapping with other character codes may be incompatible". Therefore, I thought it was impossible to express the ".." notation.
