unicode-escapes

问题 I am trying to use the encode method of python strings to return the unicode escape codes for characters, like this: >>> print( 'ф'.encode('unicode_escape').decode('utf8') ) \u0444 This works fine with non-ascii characters, but for ascii characters, it just returns the ascii characters themselves: >>> print( 'f'.encode('unicode_escape').decode('utf8') ) f The desired output would be \u0066 . This script is for pedagogical purposes. How can I get the unicode hex codes for ALL characters? 回答1:

问题 In Python 3, suppose I have >>> thai_string = 'สีเ' Using encode gives >>> thai_string.encode('utf-8') b'\xe0\xb8\xaa\xe0\xb8\xb5' My question: how can I get encode() to return a bytes sequence using \u instead of \x ? And how can I decode them back to a Python 3 str type? I tried using the ascii builtin, which gives >>> ascii(thai_string) "'\\u0e2a\\u0e35'" But this doesn't seem quite right, as I can't decode it back to obtain thai_string . Python documentation tells me that \xhh escapes the

问题 I work with large pandas dataframes on a daily basis, which gets fed information that we parse from a webAPI (xml encoding is utf-8) local to our network. After I feed the dataframe and export as a csv file I start getting encoding errors (local machine is cp1252) which I've had to deal with the past few weeks. The solution I finally found was [here][1] under tangfucious's response. df['crumbs'] = df['crumbs'].map(lambda x: x.encode('unicode-escape').decode('utf-8')) a line of code that takes

问题 I'm trying to build a corpus from the .txt file found at this link. I believe the instances of \xad are supposedly 'soft-hyphens', but do not appear to be read correctly under UTF-8 encoding. I've tried encoding the .txt file as iso8859-15 , using the code: with open('Harry Potter 3 - The Prisoner Of Azkaban.txt', 'r', encoding='iso8859-15') as myfile: data=myfile.read().replace('\n', '') data2 = data.split(' ') This returns an array of 'words', but '\xad' remains attached to many entries in

问题 An device encodes a string "🤛🏽" as "\uD83E\uDD1B\uD83C\uDFFD" . The hexadecimal numbers represented in this string are from the UTF-16 hex encoding of the character. The Unicode code point U+1F91B, U+1F3FD gets its numbers from the UTF-32 hex encoding. Taking this later one, in Swift we can do a literal like this "\u{1F91B}\u{1F3FD}" and we will get the character "🤛🏽" as expected. How can I convert from the UTF-16 hex string "\uD83E\uDD1B\uD83C\uDFFD" to get the "🤛🏽"? I've tried taking the

问题 This question already has an answer here : ES6: Bad character escape sequence creating ASCII string (1 answer) Closed 3 years ago . If I want to print a unicode Chinese character in ES6/ES2015 javascript, I can do this: console.log(`\u{4eb0}`); Likewise, if I want to interpolate a variable into a template string literal, I can do this: let x = "48b0"; console.log(`The character code is ${ x.toUpperCase() }.`); However, it seems that I can't combine the two to print a list of, for example, 40
