However if you are already processing the data in R, then you should consider using its native utf8ToInt as described here R: How to convert characters into ASCII code?

Function to convert ASCII to a string
I'm a little confused by what you are trying to show here. What is the content of $ascii?
A sequence of ASCII-encoded characters is already a string...in ASCII encoding. Are you trying to change encodings?

Hmmm... may I ask why you want to do this? I would personally probably do the reverse, 'causr I'm more fluent in letters than in decimal codes..
However, let's rephrase your problem cl to more precisely define the goal: - you have in a table a column of ASCII chars in the range A-Z (or is it also lower case?) - you want each character to be translated with its decimal cvalue over one space and 3 digits
Bash has a powerful string / char replacement, eg
zz=CABXAB;echo ${zz//A/' 065'}
You can use a list comprehension:
>>> s = 'hi'
>>> [ord(c) for c in s]
[104, 105]
Here is a pretty concise way to perform the concatenation:
>>> s = "hello world"
>>> ''.join(str(ord(c)) for c in s)
'10410110810811132119111114108100'
And a sort of fun alternative:
>>> '%d'*len(s) % tuple(map(ord, s))
'10410110810811132119111114108100'
EDIT 2: See this comment for a more elegant solution using .NET.
EDIT: Sorry, I wasn't clear on what this actually does. It converts an array of character codes to ASCII text. Thanks u/ihaxr for pointing that out.
Because this was a source of some frustration to me today and I would like to save you all the trouble. Especially useful for converting values returned by System.DirectoryServices.
function Convert-ASCII {
param($ascii)
$letter = @()
foreach ($char in $ascii){
$char = [int[]]$char
$letter += [char[]]$char
}
$final = ("$letter").Replace(" ","")
Return $final

You have an array of bytes, turn it into an array of char, and join it into a string
PS C:\> $x = 104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100
PS C:\> [char[]]$x -join ''
hello worldOr ... not ascii:
PS C:\> $q = [int[]][char[]]'héllo wórld'
PS C:\> [char[]]$q -join ''
héllo wórldYou are probably looking for 'chr()':
>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(chr(i) for i in L)
'hello, world'
Same basic solution as others, but I personally prefer to use map instead of the list comprehension:
>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(map(chr,L))
'hello, world'
