Why doesn't my Go program use the GoRunes library correctly?

GoRunes is a Go library for processing Unicode characters. It provides a series of functions and tools to operate characters, including character classification, character collection, character comparison, case conversion, etc.

If your Go program cannot use the GoRunes library correctly, the following situations may occur:

1. The GoRunes library is not installed correctly. Before using the GoRunes library, you need to use the go get command to download the GoRunes library from GitHub. If you are using Go Mod, you need to add the corresponding dependencies in the go.mod file. Make sure the GoRunes library has been properly installed and imported into your Go program.
2. The GoRunes library function is not called correctly. The GoRunes library provides a lot of functions and tools, which can cause errors if you use incorrect functions or parameters. For example, if you want to determine whether a character is a numeric character, you should use the rune.IsDigit() function instead of the rune.IsSpace() function.
3. Character encoding problem. The Unicode character set has different encoding methods, such as UTF-8, UTF-16, etc. If your program involves character encoding conversion, characters may be garbled or Unicode characters may not be processed correctly. When using the GoRunes library, you need to ensure that your program has the character encoding set correctly to avoid these problems.
4. Program logic problem. In some cases, errors occur not because of the use of the GoRunes library, but because of problems with the program logic. When troubleshooting problems, you should first check whether the program logic is correct.

In order to avoid the above problems, you can take the following measures:

1. Learn how to use the GoRunes library. When using the GoRunes library, you should learn as much as possible about how to use the functions and tools provided by the library. You can learn by looking at the GoRunes library's documentation, sample code, and other related materials.
2. Use correct functions and parameters. When using GoRunes library functions, you should choose the correct functions and parameters to ensure that the program can correctly operate Unicode characters.
3. Use the correct character encoding. When using the GoRunes library, you should ensure that the program has the character encoding set correctly to avoid character encoding issues.
4. Carefully check the program logic. When troubleshooting, you should carefully analyze the program logic to identify possible problems. If needed, you can use debugging tools to help troubleshoot the problem.

In short, when using the GoRunes library, you should carefully learn how to use it and pay attention to avoid common problems to ensure that the program can correctly handle Unicode characters.
