The problem of character encoding seems to be very small, often overlooked by technical staff, but it can easily lead to some puzzling problems. Here is a summary of the character encoding of some of the popular knowledge, I hope to be helpful to
Character encoding: ASCII, Unicode, UTF-8, gb2312

We know that in a computer, all information is eventually represented as a binary string. Each binary bit has two states: 0 and 1. Therefore, eight binary bits can combine 256

Google's Sitemap service requires that all site maps published must be encoded in Unicode UTF-8. Google does not even allow other Unicode encodings (such as UTF-16), not to mention non-Unicode encodings such as ISO-8859-1. Technically, this means
1 ASCII codeThe relationship between English characters and bits is uniformly stipulated. The ASCII code altogether specifies a 128-character encoding. For example, the space "space" is 32 (binary 00100000), and capital A is 65 (binary 01000001).

UTF-8 is a unicode implementation method, that is, its byte structure has special requirements, so we say a Chinese character range is 0x4e00 to 0x9fa5, refers to the Unicode value, as for UTF-8 encoding, it is organized by three bytes, so we can
