如何去除文本文件中的特殊字符?(*尼克斯)

我有一个源代码文件,它是从一个网页上的一些示例代码的副本开始的。 它是在Windows下创建和编辑的,编译时没有任何问题。

但在Mac下,我会遇到很多模糊的错误,比如:

../MyProgram.cpp:1: error: stray '\255' in program
../MyProgram.cpp:1: error: stray '\254' in program
../MyProgram.cpp:1: error: stray '#' in program
../MyProgram.cpp:3:4: error: invalid preprocessing directive #i
../MyProgram.cpp:5:4: error: invalid preprocessing directive #i
../MyProgram.cpp:7:4: error: invalid preprocessing directive #i
../MyProgram.cpp:23: error: missing terminating ' character
../MyProgram.cpp:369:6: error: invalid preprocessing directive #i
../MyProgram.cpp:371:8: error: invalid preprocessing directive #i
../MyProgram.cpp:375:8: error: invalid preprocessing directive #e
../MyProgram.cpp:381:8: error: invalid preprocessing directive #e
../MyProgram.cpp:383:6: error: invalid preprocessing directive #e
../MyProgram.cpp:385:8: error: invalid preprocessing directive #i
../MyProgram.cpp:389:8: error: invalid preprocessing directive #e
../MyProgram.cpp:1: error: 'i' does not name a type
../MyProgram.cpp:53: error: 'V' does not name a type
../MyProgram.cpp:75: error: 'v' does not name a type
../MyProgram.cpp:157: error: 'l' does not name a type
../MyProgram.cpp:169: error: 'l' does not name a type
../MyProgram.cpp:187: error: 'i' does not name a type
../MyProgram.cpp:197: error: 'v' does not name a type

看起来问题出在一些特殊的角色身上。
