How to Represent Any Unicode Character In Julia?

7 minutes read

In Julia, any Unicode character can be represented using the syntax "\u" followed by the Unicode code point in hexadecimal form. For example, the Unicode character for the Greek letter "Α" can be represented as "\u0391". This allows users to easily include a wide range of Unicode characters in their Julia code for increased flexibility and internationalization.

How to compose and decompose unicode characters in Julia?

In Julia, you can easily compose and decompose unicode characters using the compose and decompose functions from the Unicode module.


Here is an example of how to compose the characters "e" and acute accent ("é"):

1
2
3
using Unicode

compose('e', '\u0301')  # Outputs 'é'


Similarly, you can decompose the composed character "é" into its constituent parts:

1
decompose('é')  # Outputs ('e', '\u0301')


You can also use the composition and decomposition functions to get information about the composition and decomposition of unicode characters:

1
2
3
composition('é')  # Outputs ("\u0065", "\u0301")
decomposition('\u0065')  # Outputs (from("LATIN SMALL LETTER E"), nothing, nothing)
decomposition('\u0301')  # Outputs (from("COMBINING ACUTE ACCENT"), nothing, nothing)


These functions are useful for working with unicode characters in Julia and for manipulating text in different languages.


How to create a unicode character using the code point in Julia?

In Julia, you can create a Unicode character using the Char type and specifying the code point as an integer. Here's an example of how to create a Unicode character using the code point:

1
2
3
code_point = 0x1F600   # Unicode code point for the grinning face emoji
emoji = Char(code_point)
println(emoji)


In this example, we specify the code point 0x1F600 which represents the grinning face emoji. We then use the Char type to create a character from the code point and store it in the variable emoji. Finally, we print out the emoji character using println(emoji).


How to display a unicode character in a Julia string literal?

To display a Unicode character in a Julia string literal, you can use the \u escape sequence followed by the Unicode code point of the character.


For example, to display the Unicode character for the Greek letter theta (θ) in a Julia string literal, you can use the following code:

1
println("Unicode character for theta: \u03B8")


When you run this code, it will output:

1
Unicode character for theta: θ


You can find the Unicode code point for a specific character by looking it up in the Unicode character table or using online resources such as unicode.org.
