These codepoints will affect the presentation of the preceding character. Variation selectors are another set of codepoints that only affects their surrounding character. Left-To-Right Embedding ( U+202A) is a codepoint that forces text to be interpreted as left-to-right. ZWJ ( U+200D) is a zero width joiner and is a codepoint that joins two codepoints together. Some codepoints do not map to a displayed character. For example, diacritical codepoints such as the “combining acute accent” (U+0301) is used to append an accent on a character. Some codepoints can affect their surronding characters. Unicode has a large library of codepoints that handles characters from different languages, symbols used in pronunciation, and even emojis. BiDi, Block, Script, etc)įor example, U+0041 is a codepoint that represents the letter A.

Codepoints also have properties/attributes that describe how to perform rendering on them. BinaryĪ codepoint is a unique number that represents some type of character + information. The tradeoff however is that it will use the most memory per codepoint.įor example: In UTF-8 the letter A is represented as the following: Binary 01000001 => Codepoint (U+0041).įor characters that might require multiple 4 bytes like the treble clef 𝄞, the encoding will change depending on the schema.

UTF-32 - This is a fixed width for 32 bits that can support all codepoints.

Generally used if you only need to support most languages/symbols.

UTF-16 - This is a variable length (1 or 2 bytes) 16 bit encoding scheme that can support most codepoints while using less memory than UTF-32.

UTF-8 - This is a variable length 8 bit encoding scheme that saves the most memory for the first 127 values (in a single byte) but can also grow in size all the way up to 6 bytes depending on the codepoint.

The main difference between encoding schemas is how much memory is reserved for each codepoint.

When the program needs to use the string again, it fetches the binary and decodes it back to the string with the encoding schema.

Program will transform the string into binary and store it.

(Note: Generally this fallsback to the default encoding scheme) User inputs a string while specifying the codepoint encoding.Imagine this as a mapping between binary and codepoints. The most commonly used encodings are UTF-8 and UTF-16.

You can search for any online resource to get more familiar with this concept.Ĭodepoint encoding is a way for software to convert codepoints to assigned bytes while codepoint decoding will transform bytes back to characters. Chrome uses the ICU library for Unicode: ICU which is an open source set of libraries that provide Unicode support for many different applications.īinary and Codepoint encoding are CS concepts with a lot of online resources. The document is catered towards explaining niche concepts while also providing some pitfalls to avoid.Ĭhrome deals with Unicode hence this assumes text will be rendered as unicode characters. This is a general overview of how text gets transformed from raw bytes to a glyph on the screen. This document goes over general concepts of Unicode and text rendering.
