Make sure your environement and your variable are correctly set
For troubleshooting purpose, if necessary, add some lines to display the values of the variables just before you use them so you can check their values.
Also note that with the following, replacement will directly apply in $file :

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);
int
isalnum_l(int c, locale_t loc);
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 (with their numeric values shown 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''
The isalnum_l() function takes an explicit locale argument, whereas the isalnum() function uses the current global or per-thread locale.
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), isalpha(3), isdigit(3), iswalnum(3), xlocale(3), ascii(7)STANDARDS
The isalnum() function conforms to ISO/IEC 9899:1990 (``ISO C90''). The isalnum_l() function conforms to IEEE Std 1003.1-2008 (``POSIX.1'').
