isascii
isascii(c::Union{Char,AbstractString}) -> Bool
Tests whether a character belongs to the ASCII character set, or whether this is true for all elements of a string.
Examples
-
Check if a character is ASCII:
julia> isascii('A') true -
Check if a string contains only ASCII characters:
julia> isascii("Hello World!") true - Handle non-ASCII characters:
julia> isascii('๐') false
Common mistake example:
julia> isascii("ใใใซใกใฏ")
ERROR: MethodError: no method matching isascii(::String)In this example, the isascii function is applied to a string containing non-ASCII characters. The isascii function only works with characters or strings containing ASCII characters, so make sure to check the input before using the function to avoid such errors.
