Frequently Asked Questions
为什么字节数与字符数不同？▼
在UTF-8编码中，ASCII字符（英文字母、数字）使用1字节，韩文字符使用3字节，某些表情符号使用4字节。'안녕'是2个字符但6个字节。字节数在存储、数据库字段和API负载限制中很重要。
韩文文本的单词如何计数？▼
韩文单词与英文一样按空格计数。但韩文可能有没有空格的长复合词，导致单词计数低于预期。对于更准确的韩文文本测量，字符计数（不含空格）通常更有用。
社交媒体有哪些字符限制需要了解？▼
Twitter/X：280字符。Instagram说明：2,200字符。Facebook帖子：63,206字符。YouTube标题：100字符。LinkedIn帖子：3,000字符。Meta描述（SEO）：155-160字符。这些限制计算所有字符，包括空格和表情符号。
