Check if a string contains a non-ASCII value in Julia – ascii() Method
The ascii()
is an inbuilt function in Julia which is used to convert a specified string to a String type and also check the presence of ASCII data. If the non-ASCII byte is present, throw an ArgumentError indicating the position of the first non-ASCII byte.
Syntax: ascii(s::AbstractString) Parameters:
- s::AbstractString: Specified string
Returns: It returns the converted string if it contain ASCII byte else throw an ArgumentError indicating the position of the first non-ASCII byte.
Example 1:
Python
# Julia program to illustrate # the use of String ascii() method # Checking the presence of ASCII byte else # throw an ArgumentError indicating the # position of the first non-ASCII byte. # In below string, ? is the non-ASCII byte println(ascii("GFG?GFG")) |
Output:
ERROR: LoadError: ArgumentError: invalid ASCII at index 4 in "GFG?GFG"

Example 2:
Python
# Julia program to illustrate # the use of String ascii() method # Checking the presence of ASCII byte else # throw an ArgumentError indicating the # position of the first non-ASCII byte. # In below string, non-ASCII byte is not present println(ascii("w3wiki")) |
Output:
