(note that the option is the digit one; not the lowercase letter ell). And highlight the ? characters you are trying to replace. And, also show us the output from the command:
Code:
"ls" -1|od -bc
so we can see the characters that are being printed as question marks by ls when output is directed to a terminal. (The quotes around the ls are to avoid any aliases that might be in place.)

isalnum
ISALNUM(3) BSD Library Functions Manual ISALNUM(3)NAME
isalnum -- alphanumeric character test
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isalnum(int c);
DESCRIPTION
The isalnum() function tests for any character for which isalpha(3) or isdigit(3) is true. The value of the argument must be representable
as an unsigned char or the value of EOF.
In the ASCII character set, this includes the following characters (preceded by their numeric values, in octal):
060 ``0'' 061 ``1'' 062 ``2'' 063 ``3'' 064 ``4''
065 ``5'' 066 ``6'' 067 ``7'' 070 ``8'' 071 ``9''
101 ``A'' 102 ``B'' 103 ``C'' 104 ``D'' 105 ``E''
106 ``F'' 107 ``G'' 110 ``H'' 111 ``I'' 112 ``J''
113 ``K'' 114 ``L'' 115 ``M'' 116 ``N'' 117 ``O''
120 ``P'' 121 ``Q'' 122 ``R'' 123 ``S'' 124 ``T''
125 ``U'' 126 ``V'' 127 ``W'' 130 ``X'' 131 ``Y''
132 ``Z'' 141 ``a'' 142 ``b'' 143 ``c'' 144 ``d''
145 ``e'' 146 ``f'' 147 ``g'' 150 ``h'' 151 ``i''
152 ``j'' 153 ``k'' 154 ``l'' 155 ``m'' 156 ``n''
157 ``o'' 160 ``p'' 161 ``q'' 162 ``r'' 163 ``s''
164 ``t'' 165 ``u'' 166 ``v'' 167 ``w'' 170 ``x''
171 ``y'' 172 ``z''
RETURN VALUES
The isalnum() function returns zero if the character tests false and returns non-zero if the character tests true.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The iswalnum() function should be used instead.
SEE ALSO ctype(3), isalnum_l(3), isalpha(3), isdigit(3), iswalnum(3), ascii(7)STANDARDS
The isalnum() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
