特殊字符转int，然后返回
所以我想要的是将字母“a”转换为97（例如在ASCII表中），然后将67转换为“a”。 实际上，我执行了大量数学运算，将其视为二进制数 - 因此转换是必要的。 然而，对于特殊字符，它的效果并不好。
char c = 'ÿ';
int i = int(c);
wchar_t wTemp = static_cast<wchar_t>(i);
wchar_t* w = &wTemp;
String^ newI = gcnew String(w);
该符号只是我在图像中发现的随机符号（需要读取的字符类型）。它只是作为一个完全不同的符号出现。我不知道为什么，或者该怎么办？
So what I want, is for example to convert the letter 'a' into 97 (such as it is in the ASCII table), and then convert 67 into 'a'.
I actually perform a load of mathematics and stuff to the letter, treating it as binary number - so the transition is necessary.
However for special characters it is not working nicely.
char c = 'ÿ';
int i = int(c);
wchar_t wTemp = static_cast<wchar_t>(i);
wchar_t* w = &wTemp;
String^ newI = gcnew String(w);
That symbol is just a random one I found in an image (the type of character that will need to be read). It just comes out as a completely different symbol. I have no idea why, or what to do?

0x7f (127) 以上的字符可能会转换为负整数值。也许将
c更改为无符号：Characters above 0x7f (127) are probably converting to negative integer values. Maybe change
cto unsigned:尽管我没有运行你的代码，但我看起来不太正确。下面是来自 MSDN 的一个很好的示例，说明如何在 wchar_t 之间进行转换：

我不认为“特殊”字符有什么特别之处。
Your code doesn't look quite right to me though I didn't run it. Here is a good example from MSDN how to convert from and to wchar_t:

I don't believe there is anything special about 'special' characters.
