Small caps text uses Unicode characters from the Phonetic Extensions and Modifier Letter blocks. These characters appear as大写字母的较小版本, creating a distinctive typographic effect.
Small caps are commonly used in typography for acronyms, abbreviations, and to create visual hierarchy in text. They provide a more refined and professional appearance compared to regular uppercase letters.
Small caps text is different from regular font styling. While CSS can create small caps effects, Unicode small caps characters work consistently across all platforms and don't require special font support.
