Custom encoder

[kotyara85]

Hey there,
So i'm trying to mask string fields coming in and added a wrapper around encoder, but AddString doesn't work as expected (not called at all)

package main

import (
	"fmt"
	"os"

	"go.uber.org/zap"
	"go.uber.org/zap/zapcore"
)

type jsonEncoder struct {
	zapcore.Encoder
}

func (e *jsonEncoder) AddString(key, value string) {
	fmt.Println(key, value)
	e.Encoder.AddString("O", "Z")
}

func main() {

	logger := NewLogger()

	logger.Sugar().Infow("OK", "ok", "ok")
	logger.Debug("Debug")

}

func NewLogger(options ...zap.Option) *zap.Logger {
	encoderCfg := zapcore.EncoderConfig{
		TimeKey:        "ts",
		LevelKey:       "level",
		NameKey:        "logger",
		FunctionKey:    zapcore.OmitKey,
		MessageKey:     "msg",
		StacktraceKey:  "stacktrace",
		LineEnding:     zapcore.DefaultLineEnding,
		EncodeLevel:    zapcore.LowercaseLevelEncoder,
		EncodeTime:     zapcore.EpochTimeEncoder,
		EncodeDuration: zapcore.SecondsDurationEncoder,
		EncodeCaller:   zapcore.ShortCallerEncoder,
	}
	encoder := &jsonEncoder{zapcore.NewJSONEncoder(encoderCfg)}
	core := zapcore.NewCore(encoder, os.Stdout, zap.DebugLevel)
	return zap.New(core).WithOptions(options...)
}

Help is appreciated, Thanks!
