Thanks for the quick reply. The system locale is zh_TW.Big5. However,
I've tried setting it to "C" but the test case still fails.
In order to check if it's a locale bug, I've written a C program:
#include <locale.h>
#include <stdio.h>
#include <string.h>
int main() {
char *s1 = "\xe4\xba\x8c";
char *s2 = "\xe4\xba\x94";
setlocale(LC_ALL, "en.UTF-8");
//setlocale(LC_ALL, "zh.Big5"); //doesn't make any difference
printf("%d\n", strcoll(s1, s2));
return 0;
}
and compiled it and run it on that computer. It prints -1.
It means that strcoll is working.

Does it matter? The encoding provided to initdb is just
a default for the databases to be created in the future.
When I used createdb, I did specify "-E unicode".
