character-encoding

问题 Can anyone please explain me why the NFD normalization from U+2126 (Ω) and U+03A9 (Ω) results in the same representation and does not preserve the code point? I would have expected this behaviour for NFKD and NFKC (and for characters with diacritics) only. result1 = unicodedata.normalize("NFD", u"\u2126") result2 = unicodedata.normalize("NFD", u"\u03A9") print("NFD: " + repr(result1)) print("NFD: " + repr(result2)) Output: NFD: u'\u03a9' NFD: u'\u03a9' 回答1: These are known as "singleton

问题 I work on a java project where labels are externalized and translated into .properties files. Resources in java are read using ISO-8859-1 encoding and thus the .properties files are also stored in ISO-8859-1 encoding. The current files are messed up, sometimes using escapes \u00E4 and sometimes using the actual letter öäü . Also I have russian translations which look like this: code.adr=\u0430\u0434\u0440\u0435\u0441 This could be stored in clear text using UTF-8. Now the question is, why not
