The first 128 code points are the same as in ASCII. But it says UTF-8 can support up to million of characters? How does this work? 回答1 UTF-8 does not use one byte all the time, it's 1 to 4 bytes. The first 128 characters (US-ASCII) need one byte. The next 1,920 characte...
Subject: RE: How many Chinese characters can be stored in varchar(n chars) character set utf8? Hmm.. Especially the error message caused misunderstanding, 21 bytes can not be inserted into 24 bytes? *** ERROR[8402] A string overflow occurred during the evaluation of a character expression. ...
ucs2 has 2-byte codes. You can see them with SELECT HEX(col). Please do this to show what the bytes look like. (Seeing the character does not help -- too many other things could be fiddling with it.) utf8 uses 1- to 3-byte codes. ...

in many programming languages, you can convert a character to its ascii value using the built-in functions or operators provided by the language. for example, in python, the ord() function returns the ascii value of a character. in c++, you can use the type casting operator (int) to ...

We are having problems rendering special characters in Apache and Tomcat from EWS 1.0.1 even though that same code worked fine on our old Sun web and app servers. We believe we need UTF-8 throughout, but the code specifies different character sets. We are asking the developers to clean th...
Because host names are encoded in UTF-8 format, they do not necessarily have only 1 byte per character. ASCII characters are 1 byte each, but the size of extended characters is more than 1 byte. For details of naming restrictions and a fuller description of UTF8, see “Naming Restrictions...
