Whitespace Characters
Invisible characters including spaces, tabs, newlines, and carriage returns that affect text layout.
Chi tiết kỹ thuật
Whitespace relates to the Unicode standard, which assigns a unique code point (U+0000 to U+10FFFF) to every character across all writing systems. UTF-8 encoding uses 1-4 bytes per character — ASCII characters take 1 byte while CJK ideographs take 3 bytes. UTF-16 uses 2 or 4 bytes and is the internal string format in JavaScript and Java. Proper encoding declaration prevents mojibake (garbled text) when files cross system boundaries.
Ví dụ
```javascript // Whitespace: text processing example const input = 'Sample text for processing'; const result = input .trim() .split(/\s+/) .filter(Boolean); console.log(result); // ['Sample', 'text', 'for', 'processing'] ```
