Convert binary to utf 8 linux3/8/2024 Note that most Unicode code charts will refer to a code point by its hexadecimal (hex) representation, e.g. In Elixir you can use a ? in front of a character literal to reveal its code point: iex> ?a 97 iex> ?ł 322 This numerical index is known as a Code Point. Unicode organizes all of the characters in its repertoire into code charts, and each character is given a unique numerical index. The Unicode Standard acts as an official registry of virtually all the characters we know: this includes characters from classical and historical texts, emoji, and formatting and control characters as well. In order to facilitate meaningful communication between computers across multiple languages, a standard is required so that the ones and zeros on one machine mean the same thing when they are transmitted to another. To understand strings in Elixir, we have to educate ourselves about Unicode and character encodings, specifically the UTF-8 encoding. Although strings are one of the most common data types in computer languages, they are subtly complex and are often misunderstood. In this chapter, we will gain clarity on what exactly binaries are, how they relate to strings, and what single-quoted values, 'like this', mean in Elixir. In "Basic types", we learned a bit about strings and we used the is_binary/1 function for checks: iex> string = "hello" "hello" iex> is_binary ( string ) true Settings View Source Binaries, strings, and charlists
