資源簡介
QRCode二維碼維碼支持中文，網上流傳很多版本都說支持中文二維碼。看過測試都有問題，自己看了源碼改了下。
原版本 中有 IsUnicode 方法判斷是否為Unicode編碼 但這個方法好像有問題 所以無法準確判斷中文。可以通過改寫這個來實現中文。
另外有兩個方法 都可以解決中文問題
public virtual String decode(QRCodeImage qrCodeImage, Encoding encoding)
public virtual String decode(QRCodeImage qrCodeImage)
因為是虛方法可以重寫這個方法就可以
所以 可以通過
改寫IsUnicode 和 重寫 這個兩個虛方法來實現

public static bool IsUnicode(byte[] byteData)
{
// This is by Joson Jiang 用于判斷中文
//因為ascii編碼當中的最大為127，這樣判斷后，
//就能正確的判斷是不是unicode，這樣就能正確的解碼中文了.
bool isUnicode = false;
try
{
foreach (byte value in byteData)
{
if (value > 128)
{
isUnicode = true;
break;
}
}
}
catch (Exception)
{
//其中的是原本的代碼 無法正確判斷 中文
string value1 = FromASCIIByteArray(byteData);
string value2 = FromUnicodeByteArray(byteData);
byte[] ascii = AsciiStringToByteArray(value1);
byte[] unicode = UnicodeStringToByteArray(value2);
if (ascii[0] != unicode[0])
return true;
return false;
}
return isUnicode;//返回是不是Unicode編碼
}
