utf-8

问题 I have created one php page with UTF-8-BOM encoding. I want to use this encoding because I have some content which are in my regional language, and do display it properly i need to use UTF-8-BOM encoding. Now I want to use session with this page but it is throwing error of headers already set. So is there any way i can use both together. If I am trying to use UTF-8 only I am not getting problem displaying data in regional format. See Attached Image 回答1: The "Byte Order Mark" is a sequence of

问题 I am using testNG with selenium. I have two kind of logger, one is log4j logger and the other is testNG Reporter.log() . Now the problem is I need to log some Chinese text. But it is coming as '????' instead of Chinese text. So I changed the log4j.properties file, just added two lines: log4j.appender.file=org.apache.log4j.DailyRollingFileAppender log4j.appender.file.encoding=UTF-16 Now in my log4j logs it is coming properly but in testNG Reporter.log() it's still coming as '?????'. Log4j log:

问题 I have a huge problem. I just updated my websites homepage to display a unicode hexagon character: ⬢ ⬢ aka U+2B22 I made it 200px big and filled it with text. It looks good and works fine on my computer. With both Internet Explorer (win8) and Firefox 28. I tested it on 5 different computers and it didn't work there! Tested with Firefox 28 and Internet Explorer (win7) on each device and on one computer even with the newest Chrome. So what am I doing wrong? How is it possible that it works on

问题 I have a problem with my application on Websphere 8.5.5 . It's a spring rest application that is used to send email. In my service I receive the mail details and I use spring to forward it to the receivers. It works fine but when I try to send messages with non ascii character the message arrives with the special characters replaced by a question mark. The UTF-8 encoding doesn't work. In my pc the application runs on Liberty Profile server and initially it doesn't work either. I googled the

问题 And also for char8_t ? I assume there is some C++20 decision, somewhere, but I could not find it. There is also P1428, but that doc is not mentioning anything about printf() family v.s. char8_t * or char8_t . Use std::cout advice might be an answer. Unfortunately, that does not compile anymore. // does not compile under C++20 // error : overload resolution selected deleted operator '<<' // see P1423, proposal 7 std::cout << u8"A2"; std::cout << char8_t ('A'); For C 2.x and char8_t Please

问题 I wrote this function that creates a random string of UTF-8 characters. It works well, but the regular expression [^\p{L}] is not filtering all non-letter characters it seems. I can't think of a better way to generate the full range of unicode without non-letter characters.. short of manually searching for and defining the decimal letter ranges between 65 and 65533. function rand_str($max_length, $min_length = 1, $utf8 = true) { static $utf8_chars = array(); if ($utf8 && !$utf8_chars) { for (

问题 I work with utf-8 strings. They should be stored in a MySQL database table. That's why I decided to choose some of utf-8 collations for several columns. Now I see the choice in not as clear as I guessed. The problem is the SELECT statement should be case sensitive. But it is not. The first option is to choose another utf-8 collation (the only non-ci collation is utf8_bin as far as I see). Is it a solution? The second one is to use BINARY in the SELECT statement: select col1, col2 from table1
