The length of Chinese Characters in Oralce and the length of oralce Chinese Characters Generally, we use the String. length () method when verifying the String length at the Java layer. The returned length is the same in both Chinese and English. However, after a database is inserted, an error is reported (the length exceeds the limit ). Public class StringLength {public static void main (String [] args) {

Javascript converts two-byte characters into single-byte characters and calculates the length. It is a javascript byte. Copy codeThe Code is as follows: function (s ){Return Math. ceil (s. replace (/[\ u4e00-\ u9fa5]/g, 'xx'). length/2 );} You can also use (/[^ \ x00-\ xff]/g, '**') to replace the double byte character '**'.(/[\ U4e00-\ u9fa5]/g, '**') Is it a unicode encoding that replaces Chinese

When we use system. Io. streamreader to read TXT files containing Chinese characters, we often read garbled characters (streamwriater writes text files There is a similar problem), the reason is very simple, that is, the file encoding (encoding) does not match the streamreader/writer encoding. To solve this problem, I wrote a class to obtain the encoding of a text file. In this way, we can create the corr

Some symbols cannot be directly transmitted in the URL. If you want to pass these special symbols in the URL, you need to use their encoding. The encoding format is % plus the characters' ASCII code, that is, a percent sign %, followed by the corresponding characters' ASCII (hexadecimal) code value. For example, the Space Encoding value is "% 20 ". If no escape character is used, the encoding will be treat

I wrote a tool a long time ago. Now I have not developed software in Japan, so I almost forgot it. Let's share it with you today. I personally think this little tool is quite useful, because we Chinese people can easily remember those Japanese characters, but often cannot remember the corresponding Japanese pronunciation, so I wrote this little thing. Its functions include: 1. Search for Japanese characters
