UTF-32
UTF-32 is a technical specification used primarily in computing and software engineering. It is characterized by its fixed-width nature, meaning every single character occupies exactly 32 bits of memory, regardless of the character's complexity or origin.
This fixed-width property makes it computationally efficient for indexing and random access within a string, as the position of any character can be calculated via simple multiplication. However, this efficiency comes at the cost of significant memory overhead compared to variable-width encodings like UTF-8, making it rare for data transmission or storage and more common for internal processing within specific application environments.
Ý nghĩa
Ví dụ
The application uses utf32 to ensure every character has a fixed width.
Why would anyone use utf32 when it consumes so much memory?
I need to convert this string from utf8 to utf32 for the internal processing logic.
Using utf32 makes indexing characters much faster because they are all the same size.
The system crashed because the buffer was not large enough for the utf32 encoded text.
Let's check if the library supports utf32 for these specific Unicode planes.
UTF-32 is simple but inefficient for storing standard English text.
I wonder if switching to utf32 will solve the surrogate pair issue in my code.
