Metric Fast Development platform There is a Len in the base function that gets the character length function. The specific usage is:len ("123ABC string")The result of this method is: 9that is, the total number of characters, without distinguishing between single-byte and double-byte cases. If a field is set to a length of 9, then this string is saved to the database, it will prompt the string is too long, b

relationship here is that UTF-8 is one of the ways Unicode is implemented.One of the biggest features of UTF-8 is that it is a variable-length coding method. It can use 1~4 bytes to represent a symbol, varying the length of a byte depending on the symbol.The coding rules for UTF-8 are simple, with only two lines:1) for a single-byte symbol, the first bit of the byte is set to 0, and the next 7 bits are the

Remember vamcily once asked me: "Why get the length of an array with. Length (in the form of a member variable), and get the length of a string with. Length (in the form of a member method). ” At that time, I thought it was reasonable to ask. To do the same thing, why use two different styles of style? Moreover, the a
