Some non english characters are missing when decompressing

[skipness]

When decompressing string which have non english characters, some of them will become blank space, for example:

String chi_t = "測試";
String chi_s = "测试";
String jpy = "テスト";
String eng = "testing";

String compressed_chi_t = LZString.compress(chi_t);
String compressed_chi_s = LZString.compress(chi_s);
String compressed_jpy = LZString.compress(jpy);
String compressed_eng = LZString.compress(eng);

String decompressed_chi_t = LZString.decompress(compressed_chi_t);
String decompressed_chi_s = LZString.decompress(compressed_chi_s);
String decompressed_jpy = LZString.decompress(compressed_jpy);
String decompressed_eng = LZString.decompress(compressed_eng);

// Output
// 測
// 测
// テ
// testing
