How do I accomplish random reads of a UTF8 file

阅读更多关于 How do I accomplish random reads of a UTF8 file

问题 My understanding is that reads to a UTF8 or UTF16 Encoded file can't necessarily be random because of the occasional surrogate byte (used in Eastern languages for example). How can I use .NET to skip to an approximate position within the file, and read the unicode text from a semi-random position? Do I discard surrogate bytes and wait for a word break to continue reading? If so, what are the valid word breaks I should wait for until I start the decoding? 回答1: Easy, UTF-8 is self-synchronizing

问题 So I know how to convert String to utf8 format like this for character in strings.utf8 { // for example A will converted to 65 var utf8Value = character } I already read the guide but can't find how to convert Unicode code point that represented by integer to String. For example: converting 65 to A. I already tried to use the "\u"+utf8Value but it still failed. Is there any way to do this? 回答1: If you look at the enum definition for Character you can see the following initializer: init(_

I was using spyder-ide while parsing a tumblr page with the permission of the author, and at some point everything just crashed. Even my linux system had freezed. Well, to cut to the chase now I can not start spyder, it gives me the following error after I had written spyder to my terminal: Traceback (most recent call last): File "/home/dk/anaconda3/bin/spyder", line 2, in <module> from spyderlib import start_app File "/home/dk/anaconda3/lib/python3.5/site-packages/spyderlib/start_app.py", line 13, in <module> from spyderlib.config import CONF File "/home/dk/anaconda3/lib/python3.5/site

Python Saving JSON Files as UTF-8

阅读更多关于 Python Saving JSON Files as UTF-8

问题 I'm trying to output some UTF-8 characters to a JSON file. When I save the file they're being written like this: {"some_key": "Enviar invitaci\u00f3n privada"} The above is valid and works. When I load the file and print 'some_key' it displays "Enviar invitación privada" in the terminal. Is there anyway to write the JSON file with "some_key" as the encoded version, like this? {"some_key": "Enviar invitación privada"} 回答1: Set ensure_ascii to False : >>> print json.dumps(x, ensure_ascii=False)

Ruby: Checking for East Asian Width (Unicode)

阅读更多关于 Ruby: Checking for East Asian Width (Unicode)

Using Ruby, I have to output strings in an columnar format to the terminal. Something like this: | row 1 | a string here | etc | row 2 | another string | etc I can do this fine with Latin UTF8 characters using String#ljust and %s. But a problem arises when the characters are Korean, Chinese, etc. The columns simply won't align when there are rows of English interspersed with rows containing Korean, etc. How can I get column alignment here? Is there a way to output Asian characters in the equivalent of a fixed-width font? How about for documents that are meant to be displayed and edited in Vim?
