Unicode

Unicode character utilities for CTBase.

This module provides functions for converting integers to Unicode subscript and superscript characters, useful for mathematical notation and display.

ctindice(i::Int64) -> Char

Return the integer i ∈ [0, 9] as a Unicode subscript character.

Throws an CTBase.Exceptions.IncorrectArgument exception if i is outside this range.

The Unicode subscript digits start at codepoint U+2080 for '0' and continue sequentially.

Example

julia> using CTBase

julia> CTBase.ctindice(3)
'₃': Unicode U+2083 (category No: Number, other)

ctindices(i::Int64) -> String

Return the integer i ≥ 0 as a string of Unicode subscript characters.

Throws an CTBase.Exceptions.IncorrectArgument if i is negative.

Example

julia> using CTBase

julia> CTBase.ctindices(123)
"₁₂₃"

ctupperscript(i::Int64) -> Char

Return the integer i ∈ [0, 9] as a Unicode superscript (upper) character.

Throws an CTBase.Exceptions.IncorrectArgument exception if i is outside this range.

Note: Unicode superscripts ¹ (U+00B9), ² (U+00B2), and ³ (U+00B3) are special cases. The other digits ⁰ (U+2070) and ⁴ to ⁹ (U+2074 to U+2079) are mostly contiguous.

Example

julia> using CTBase

julia> CTBase.ctupperscript(2)
'²': Unicode U+00B2 (category No: Number, other)

ctupperscripts(i::Int64) -> String

Return the integer i ≥ 0 as a string of Unicode superscript characters.

Throws an CTBase.Exceptions.IncorrectArgument if i is negative.

Example

julia> using CTBase

julia> CTBase.ctupperscripts(123)
"¹²³"
