Hi,
I am facing an issue in comparing two urls (below).
1)  "https://domain.org/v1.0/users/[email protected]";
2)   "https://domain.org/v1.0/users/test%40user.org";

Comparison of the two strings is failing due to mismatch of '%40'  and (@)
character even though the both urls are the same.
 (gdb) p url
$1 = 0x55d35cfbd1f8 "https://domain.org/v1.0/users/[email protected]";
(gdb) p graph_url
$2 = 0x7ffd82777240 "https://domain.org/v1.0/users/test%40user.org";

Can you please let me know how to compare these two strings.
One way I could think of is convert both the strings to utf-8 but don't
find an utility function to compare the UTF-8 strings.

Thanks,
Mahendrakar.

They aren't multi-byte; converting them to UTF-8 wouldn't change
anything. As is, they are in fact different strings, as "URL" is
something only browsers know about.

You probably need to urldecode (or encode) them in your programming
language before storing them.
