I like the tr solution.
But it needs \n to not fold the lines.
Retain the original number positions:
Sqeeze the space to one:
BTW with sed these are
In \{n,m\} a missing m means "at least n".
In ERE this is {n,m} - but some awk do not have it implemented (and {1,} is the same as +).

iswcntrl
ISWCNTRL(3) Linux Programmer's Manual ISWCNTRL(3)NAME
iswcntrl - test for control wide character
SYNOPSIS
#include <wctype.h>
int iswcntrl(wint_t wc);
DESCRIPTION
The iswcntrl() function is the wide-character equivalent of the iscntrl(3) function. It tests whether wc is a wide character belonging to
the wide-character class "cntrl".
The wide-character class "cntrl" is disjoint from the wide-character class "print" and therefore also disjoint from its subclasses "graph",
"alpha", "upper", "lower", "digit", "xdigit", "punct".
For an unsigned char c, iscntrl(c) implies iswcntrl(btowc(c)), but not vice versa.
RETURN VALUE
The iswcntrl() function returns nonzero if wc is a wide character belonging to the wide-character class "cntrl". Otherwise it returns
zero.
CONFORMING TO
C99.
NOTES
The behavior of iswcntrl() depends on the LC_CTYPE category of the current locale.
