character-encoding

问题 I have a website which allows users to input usernames. The problem here is that the code in c++ assumes the browser encoding is Western Europe and converts the string received from the username text box into unicode to compare with string stored within the databasse. with the right browser encoding set the character úser is recieved as %FAser and coverted properly to úser within the program however with the browser settings set to UTF-8 the string is recieved as %C3%BAser and then converted

问题 I'm quite new to C programming, and I have some problems trying to assign a value over 127 (0x7F) in a char array. In my program, I work with generic binary data and I don't face any problem printing a previously acquired byte stream (e.g. with fopen or fgets, then processed with some bitwise operations) as %c or %d. But if I try to print a character from its numerical value like this: printf("%c\n", 128); it just prints FFFD (the replacement character). Here is another example: char abc[] =

问题 I have a python 3 program that monitors a log file. The log includes, among other things, chat messages written by users. The log is created by a third party application which I cannot change. Today a user wrote "텋��텋��" and it caused the program to crash with the following error: future: <Task finished coro=<updateConsoleLog() done, defined at /usr/local/src/bserver/logmonitor.py:48> exception=UnicodeDecodeError('utf-8',... say "\xed\xa0\xbd\xed\xb1\x8c"\r\n', 7623, 7624, 'invalid

问题 I download messages from a Gmail account using POP3 and save them in a SQLite database for futher processing: mailbox = poplib.POP3_SSL('pop.gmail.com', '995') mailbox.user(user) mailbox.pass_(password) msgnum = mailbox.stat()[0] for i in range(msgnum): msg = '\n'.join(mailbox.retr(i+1)[1]) save_message(msg, dbmgr) mailbox.quit() However, looking in the database, all lines but the last one of the message body (payload) have trailing equal signs. Do you know why this happens? 回答1: Frederic's

I researched a lot on SO and could not find anything similar to this problem. api_url = self.api_base+'/street2coordinates' api_body = json.dumps(addresses) #api_url=api_url.encode("utf-8") #api_body=api_body.encode("utf-8") print(type(api_url)) response_string = six.moves.urllib.request.urlopen(api_url, api_body).read() response = json.loads(response_string) If I do not encode the api_url and api

问题 Hello wise men & women, How would you select the first x bytes of a string? The use case: I'm optimizing product description texts for upload to Amazon, and Amazon measures field lengths by bytes in utf8 (not latin1 as I stated earlier), not by characters. MySQL on the other hand, seems to operate character-based. (e.g., the function left() is character-based, not byte-based). The difference (using English, French, Spanish & German) is roughly 10%, but it can vary widely. Some tests
