unicode

问题 I'm trying to read and write a dataframe to a pipe-delimited file. Some of the characters are non-Roman letters (`, ç, ñ, etc.). But it breaks when I try to write out the accents as ASCII. df = pd.read_csv('filename.txt',sep='|', encoding='utf-8') <do stuff> newdf.to_csv('output.txt', sep='|', index=False, encoding='ascii') ------- File "<ipython-input-63-ae528ab37b8f>", line 21, in <module> newdf.to_csv(filename,sep='|',index=False, encoding='ascii') File "C:\Users\aliceell\AppData\Local

问题 I was surprised to find that no Unicode normalization of the Ł character maps it to something like L + combining stroke . That was my best explanation to understand why Ł to get mapped to L rather than ? when converting from a Unicode-capable encoding to ASCII or a code page that doesn't have the Ł character. How does it work otherwise? Does the standard define fallback characters? 来源： https://stackoverflow.com/questions/58674948/how-does-unicode-conversion-to-ascii-know-to-map-%c5%81-to-l

问题 In a web application, I have to display a special unicode character, know as BLACK DIAMOND (U+25C6) (see here for more details). Here is a sample : ◆ The font defined for the page is Arial, with size 13px. Surprisingly, the character is rendered with a bigger size in IE6 vs other browsers (FF, Chrome, ...). Is there any reason of this weird behavior and what is the solution to avoid this ? 回答1: This is because the specified character is missing from the font you specified. So the browser

问题 python and tkinter are processing unicode characters correctly. But they are not able to display unicode encoded characters correctly. I am using Python 3.1 and tkinter in Ubuntu. I am trying to use Tamil unicode characters. All the processing are done correctly. But the display is wrong?

问题 Consider I have a Unicode string (Not the real unicode but the string that looks like unicode). and I want to get it's utf-8 variant. How can I do it in Python? For example If I have String like: title = "\\u10d8\\u10e1\\u10e0\\u10d0\\u10d4\\u10da\\u10d8 == \\u10d8\\u10d4\\u10e0\\u10e3\\u10e1\\u10d0\\u10da\\u10d8\\u10db\\u10d8" How Can I do it so that I get its utf-8 variant (Georgian symbols): ისრაელი == იერუსალიმი To say it simply I want to Have code like: title = "\\u10d8\\u10e1\\u10e0\

问题 While making a translation to a YouTube video (translations can only be in Unicode, no other markup is possible as far as I know of), I stumbled across the concentration of H + in orange juice. It is supposed to be one times ten to the negative 3.5 molar. I'd like to write it down as "1·10 -3,5 M" (mind the comma, it is translated to dutch). The problem is that I can not find a superscript comma or even a superscript period between all 120,520 unicode graphical characters. Does someone have

问题 I have a large text file that contains a few unicode characters that make LaTeX crash. How can I find non-ASCII characters in a file with sed, and the like in a Linux bash? 回答1: Try: nonascii() { LANG=C grep --color=always '[^ -~]\+'; } Which can be used like: printf 'ŨTF8\n' | nonascii Within [] ^ means "not". So [^ -~] means characters not between space and ~. So excluding control chars, this matches non ASCII characters, and is a more portable though slightly less accurate version of [^
