代码 128 编码字符串错误

Question

我已经从这个网站安装了 code128 字体的 C：/windows/fonts我使用 java 方法生成条形码字符串，但是当我将结果字符串放入 MS word 中时，我有这个

知道我已经安装了字体并使用来自同一网站的代码的问题在哪里

Answer 1

我已将此页面的 c# 代码转换为 java 并且可以工作

这是Java代码：

    public class NewCoder128 {

    public NewCoder128(){}

     public String StringToBarcode(String value)
     {
         // Parameters : a string
         // Return     : a string which give the bar code when it is dispayed with CODE128.TTF font
         //              : an empty string if the supplied parameter is no good
         int charPos, minCharPos;
         int currentChar, checksum;
         Boolean isTableB = true, isValid = true;
         String returnValue = "";
         if (value.length() > 0)
         {
             // Check for valid characters
             for (int charCount = 0; charCount < value.length(); charCount++)
             {
                 //currentChar = char.GetNumericValue(value, charPos);
                 //            (int)char.Parse(value.Substring(charCount, 1));
                 System.out.println("count "+charCount);
                 currentChar = value.charAt(charCount);
                 if (!(currentChar >= 32 && currentChar <= 126))
                 {

                 }
             }

            }
            return MinCharPos;
        }

    }

使用此类，您只需要下载Code128字体，将其安装在系统上粘贴Windows/字体中并按如下方式调用此代码，生成的条形码将可读

NewCoder128 newCoder128 = new NewCoder128();    
String encoded_string = newCoder128.StringToBarcode("123456789")
// encoded string is    "Í,BXnÈ9oÎ"
