HarmonyOS 使用pako包进行gzip压缩解压缩的时候，解压缩后的数据比原数据少了10个字符 -

参考示例：

import { buffer, util } from '@kit.ArkTS';
import pako from 'pako'

@Entry
@Component
struct Index {
  build() {
    Column() {
      Button("截图")
        .onClick(() => {
          let s = '123456789101111111111'
          let u = new Uint8Array(buffer.from(s, 'utf-8').buffer);
          // let rowData = new util.Base64Helper().encodeToStringSync(u)
          let rowData =
