String that contains all ascii characters

Question

I want to create a string in JavaScript that contains all ascii characters. How can I do this?

Answer 1

This is a version written in python. Gives all ASCII characters in order as a single string.

all_ascii = ''.join(chr(k) for k in range(127))  # 7 bits
all_chars = ''.join(chr(k) for k in range(255))  # 8 bits
printable_ascii = ''.join(chr(k) for k in range(127) if len(repr(chr(k))) == 3)


>>> print(printable_ascii)
' !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^_`abcdefghijklmnopqrstuvwxyz{|}~'

The last string here, printable_ascii contains only those characters that contain no escapes (i.e. have length == 1). The chars like: \x05, \x06 or \t, \n which does not have its own glyph in your system's font, are filtered out.

len(repr(chr(k))) == 3 includes 2 quotes that come from repr call.
