字元計數器是什麼？
The Character Counter instantly counts characters, words, sentences, and paragraphs as you type or paste text. It's an essential tool for writers, students, social media managers, and anyone who needs to meet specific text length requirements. Many platforms enforce character limits — Twitter/X (280 characters), Instagram captions (2,200), meta descriptions (155-160), SMS messages (160), and academic abstracts (150-300 words). Exceeding these limits means your content gets cut off or rejected. This tool provides real-time counting with detailed breakdowns including characters with and without spaces, word count, average word length, sentence count, and estimated reading time. It's useful for everything from crafting tweets to writing essays and SEO meta descriptions.

常見問題
▶字數是怎麼計算的？
字數是以空白字元分隔來計算的。連續的空格和換行會被視為單一分隔符。
▶位元組是怎麼計算的？
位元組使用 UTF-8 編碼計算。ASCII 字元佔 1 個位元組，中文、日文或表情符號佔 2-4 個位元組。
▶顯示哪些 SNS 的字數限制？
我們顯示 Twitter/X（280）、Instagram 說明文字（2,200）、YouTube 標題（100）和 TikTok 說明文字（4,000）的限制。
▶What's the difference between characters with and without spaces?
Characters with spaces counts every character including space bar presses. Characters without spaces counts only letters, numbers, and punctuation. Different platforms use different counting methods — Twitter counts with spaces, while some SMS systems count without.
▶What are common character limits I should know?
Key limits: Twitter/X posts (280 chars), SMS (160 chars), Google meta title (60 chars), meta description (155-160 chars), Instagram bio (150 chars), Instagram caption (2,200 chars), LinkedIn headline (220 chars), and YouTube title (100 chars).
▶Does this tool work with all languages?
Yes. The counter works with any language including CJK characters (Chinese, Japanese, Korean), Arabic, Cyrillic, and emoji. Each character is counted individually regardless of the script or language used.
