How can I read \x1a from a file?

Question

The contents of the file I need to read are as follows.

This file is in utf-16 LE format.

테스트갚켚테스트

in utf-16 LE

ff fe 4c d1 a4 cd b8 d2 1a ac 1a cf 4c d1 a4 cd b8 d2

I can't read the whole file because of \x1a. (갚, 켚)

How can I read it as a char?

Since it is used in flex, it must be read as a char.

FILE* fp = fopen("text.txt", "r");
char str[1000];
fread(str, sizeof(str), 1, fp);
