批处理制作二维码生成器
柴飞星
本文向大家介绍批处理制作二维码生成器，包括了批处理制作二维码生成器的使用技巧和注意事项，需要的朋友参考一下
这个程序不能直接支持 Unicode, 同样不能直接支持任何双字节或多字节字符(包括汉字), 但可以用十六进制转码的方式生成包含 Unicode (或其他任何编码)字符的二维码图形.
如果数据含有UTF-8 Unicode 字符时, 在数据头部加上 BOM (\xEF\xBB\xBF) 即可.
例如:
\xEF\xBB\xBF\xE6\xB1\x89\xE5\xAD\x97
上面的代码表示中文字符 "汉字"
任何 ASCII 字符(\x00 到 \xFF)都可以用十六进制转码方式输入, 也可以用明文输入(如果可以的话), 十六进制转码用 "\x" 开头, 后跟两位十六进制.
例如: \x20 表示空格
纠错等级有4级可选: L,M,Q,H
掩码图形有 8 种可选: 0 到 7 的整数.
已更正的问题: 版本20141113, 当数据中含有双引号时, 有可能导致程序退出.
测试于 Win7 64 位 及 XP 32 位
