Conversion between Unicode, UTF8, GB2312, UCS2, and GBK Conversion of several encoding formats. Not many are used at ordinary times. However, we often encounter text message protocols. During this time, I made an SMS platform interface and

Problem Description: The project has been online for several months, has been running well, one day the system will not function properly, hibernate connection to the database problems; from the log see "cannot convert between UTF8 and UCS2: failutf8

. Net UCS2 plus codeThe simplest method. Recently, I developed a text message Gateway application. Although it is not as troublesome as PDUS, it is necessary to add a code for sending a Chinese text message (BTW does not need to be used in the end ).

UTF-8 contains the characters that all countries in the world need to use, is international code, strong universality. UTF-8 encoded text can be displayed on browsers that support UTF8 character sets in countries. For example, if the UTF8 code, the

Today, using Unicode as a string is a common sense, but it's still a headache for some programming languages with a long history. Without the support of a third-party library, C + + does not actually support Unicode effectively, even if it is UTF8. (
