Then apply the Rules summarized in the previous chapter of UTF-8 encoding, it is not difficult to find that the 6 bytes of data comply with the UTF-8 encoding rules. If the entire data stream meets this rule, we can

Original: WebSockets on IOS with StarscreamAaron DouglasTranslator: Kmyhy
Traditional network technology (i.e. Berkeley sockets) is considered to be reliable and stable. But the Berkeley socket is not very good under certain web technologies, such as proxies and firewalls. WebSocket appeared in 2011 as a new technology to establish two-way communication between client and server. WebSocket is more efficient than multiple HTTP requests and allows for long connections.It's not that easy to us

I have always wanted to use crawlers to land and crawl Twitter data, tried scrapy,requests and other packages, are not successful, may be I am not familiar with the reasons, butA new package, Tweepy, was discovered today, dedicated to handling the Twitter API in Python. Try the first example of the tutorial first, after a bit of your own modificationThe code is as follows:Tweepy Crawl Twitter Data 1 import re import tweepy auth = tweepy. Oauthhandler ("xxxxx",

when I met emoji. Assume that the limit is entered in 15 characters, and the 15th character if the input is emoji, the emoji does not display properly. Because emoji is a two-character size.So, here's the idea of preventing this rough truncation method.

It can be simply understood that UTF8MB4 is currently the largest character encoding, supporting arbitrary text.
Why would there be utf8mb4?
Since UTF8 has no problem coping with daily use, why use UTF8MB4? The lower version of MySQL supports UTF8 encoding, with a maximum character length of 3 bytes and an error if a 4-byte character is encountered. The three-byte UTF-8 maximum encoded Unicode character is 0xFFFF, which is the basic multiple plane (BMP) in Unicode. That is, any Unicode charact
