C String To Unicode Escape Sequence

UTF-16 Unicode Escape Sequences: Converting Between WEB and String Formats

WEB to String Conversion

To convert a WEB Unicode escape sequence in the UTF-16 uHHHH range to a string, perform the following steps:

1. Replace "u" with "\u".
2. For each "H" in the escape sequence, replace it with the corresponding hexadecimal digit (0-F).

For example, to convert the WEB escape sequence "u0001F601" to a string, you would replace "u" with "\u" and replace the "H"s with "1", "6", "0", and "1", resulting in the string "\u1F601".

String to WEB Conversion

To convert a string to a WEB Unicode escape sequence in the UTF-16 uHHHH range, perform the following steps:

1. Replace "\u" with "u".
2. For each hexadecimal digit (0-F) in the escape sequence, replace it with the letter "H".

For example, to convert the string "\u1F601" to a WEB escape sequence, you would replace "\u" with "u" and replace the hexadecimal digits "1", "F", "6", and "0" with "H", resulting in the escape sequence "uHHHH".

Example

The following code demonstrates the conversion process:

```csharp // Convert WEB escape sequence to string string str = "\u0022Hello World\u0022"; Console.WriteLine($"String: {str}"); // Convert string to WEB escape sequence string web = "u0001F601"; Console.WriteLine($"WEB: {web}"); ```

Conclusion

Converting between WEB and string Unicode escape sequences is a straightforward process that can be easily implemented in code. Understanding these conversions is essential for working with Unicode characters in different contexts.
