function::user_string_quoted_utf32 - Linux

Overview

function::user_string_quoted_utf32 is a utility function in C++ that converts a string into a quoted UTF-32 string. It is useful for creating strings that can be safely saved and loaded from files or databases without the risk of data corruption or misinterpretation due to encoding issues.

Syntax

std::string user_string_quoted_utf32(const std::string& string);

Parameters:

• string: The input string to be quoted and converted to UTF-32.

Options/Flags

None.

Examples

Simple Example:

std::string original_string = "Hello, world!";
std::string quoted_string = user_string_quoted_utf32(original_string);

std::cout << quoted_string << std::endl;

Output:

"Hello, world!"

Escaping Special Characters:

Special characters like quotation marks (") and backslashes () need to be escaped when converting to UTF-32.

std::string original_string = "The \"quick\" brown fox jumps over the lazy dog.";
std::string quoted_string = user_string_quoted_utf32(original_string);

std::cout << quoted_string << std::endl;

Output:

"The \"quick\" brown fox jumps over the lazy dog."

Common Issues

• Encoding Issues: If the input string contains characters that are not supported by UTF-32, they may be truncated or replaced with a substitute character (e.g., ‘?’).
• Buffer Size: Ensure that the buffer used to store the quoted string is large enough to accommodate the converted result.

Integration

function::user_string_quoted_utf32 can be used in conjunction with other commands that work with strings, such as:

• printf: To format and print quoted UTF-32 strings.
• grep: To search for patterns in quoted UTF-32 strings.
• awk: To manipulate and transform quoted UTF-32 strings.
