Background
During development, you need to determine whether an input character is a numeric character. If it is a numeric character, it is converted to an integer.
Problem proposal
The char. IsDigit method and int. TryParse method are used during implementation. It is found that char. isDigit determines it as a numeric character and uses int. the TryParse method does not recognize it as a numeric character. Why?
Problem Reproduction
Instance code

Problems encountered in the project. The comparison results of the half-width character F00000 and the full-width character F00000 are the same, leading to duplicate primary key issues. The full-width ASCII code is 0xA3A8, while the half-width is 0x28. So why does SQL Server think it is the same?

As we know, in Windows, both Chinese and full-width characters account for two bytes and use the ASCII chart 2 (codes 128–255). We can, by this point, detect whether the user entered Chinese and full-width characters. In fact, the first byte of the full-width character is always set to 163, while the second byte is the same half-
