![]() If you know what block a symbols is in, you only need to remember the last two hex digits. For example, U+22xx are math symbols and U+26xx are miscellaneous symbols. Unicode is organized into blocks of related characters. Brute force is fine for small amounts of data and short-term memory, but image association works much better for large amounts of data and long-term memory. It may not seem worthwhile to go to the effort of encoding and decoding numbers like this, but it scales well. Second, Unicode codepoints are four hex digits long (or five outside the Basic Multilingual Plane.) We’ll address both of these difficulties shortly. First, Unicode codepoints are nearly always written in hexadecimal, and so you’ll run into the letters A through F as well as digits. However, Unicode presents a couple challenges. As with everything else, the Major system becomes easier with practice. The most common way to associate an image with a number is the Major system. Inserting Unicode values gives you access to more characters in more environments.Īs with ASCII, you can memorize the Unicode value of a symbol by associating an image with a number and associating that image with the symbol. There are convenient ways of inserting common non-ASCII characters without knowing their Unicode values, but these offer a limited range of characters and they work differently in different environments. I often need to insert a π symbol, for example, and so I made an effort to remember its Unicode value, U+03C0. But knowing a few Unicode characters is handy. There are nearly 150,000 Unicode characters at the moment, and the list is grows over time. Memorizing all Unicode values would be insurmountable. Memorizing all 128 ASCII values is doable. This post is a follow up, how to memorize Unicode values. ![]() ![]() When I looked back at my traffic stats to write this month’s newsletter I noticed that a post I wrote last year about how to memorize the ASCII table continues to be popular. At the end of each month I write a newsletter highlighting the most popular posts of that month.
