[yyle88]

Describe the bug
code:

package M我勒个擦

import (
	"testing"

	"go.uber.org/zap"
)

func TestAbc(t *testing.T) {
	// 自定义 zap 配置
	config := zap.NewDevelopmentConfig()

	// 创建 logger
	logger, err := config.Build(zap.AddStacktrace(zap.PanicLevel)) // 在 Panic 级别添加堆栈
	if err != nil {
		t.Fatalf("failed to build logger: %v", err)
	}
	defer logger.Sync()

	funcName(logger)
}

func funcName(log *zap.Logger) {
	defer func() {
		recover()
	}()
	log.Panic("expect TRUE while got FALSE")
}

To Reproduce
run the test code.

Expected behavior
output is:

I know it is better not use no-ascii code in the package path.

while as you see. my english is just so so.

so I really need the chinese package path in my project. so can you please provide a stack-trace-encoder set func.

thank you very much.
