命令行GB2312,UTF8,Unicode,BIG5编码转换工具VBS版

VBS写的GB2312,UTF-8,Unicode,BIG5编码转换工具,
转换工具下载:GB2Ue.vbs (3.34 kb)

演示
echo "ABCDE &!@#$ ^<>() %% abcde 测试！"> "处理前.txt"
GB2Ue.vbs "处理前.txt" "处理后.txt"
Ue2U8.vbs "处理后.txt"
U82GB.vbs "处理后.txt"
GB2U8.vbs "处理后.txt"
U82Ue.vbs "处理后.txt"
Ue2GB.vbs "处理后.txt"
@echo 经过6次处理 "处理后.txt" 和 "处理前.txt" 仍旧是相同编码
如果不知道文件的原始编码，请使用
