# 2021-03-02 Meco Man The first version
|
|
||||||
# 2021-03-04 Meco Man 增加统一转换成UTF-8编码格式功能
|
|
||||||
|
|
||||||
|
|
||||||
#本文件会自动对指定路径下的所有文件包括子文件夹的文件（仅针对.c.h）进行扫描
|
|
||||||
# 1)将源文件编码统一为UTF-8;
|
|
||||||
# 2)将TAB键替换为空格;
|
|
||||||
# 3)将每行末尾多余的空格删除，并统一换行符为'\n';
|
|
||||||
#使用时只需要双击本文件，输入要扫描的文件夹路径即可
|
|
||||||
#不能保证100%全部成功转换为UTF-8，有一些编码特殊或识别不准确会在终端打印信息，需人工转换
|
|
||||||
|
|
||||||
#欢迎对本文件的功能继续做出补充，欢迎提交PR
