Description

When there is a cjk character on the left side, the complement appears repeated.

Steps to reproduce

open main.c in nvim

#include <stdio.h>

int main() {
    int price = 5;
    printf("价格是:%d", pr);
    return 0;
}

input pr and tab,then press enter

Expected behavior

#include <stdio.h>

int main() {
    int price = 5;
    printf("价格是:%d", price);
    return 0;
}

Actual behavior

#include <stdio.h>

int main() {
    int price = 5;
    printf("价格是:%d", pprice);
    return 0;
}
