在「ASCII ↔ 十六进制」中，先在上方输入或粘贴内容，然后点击「→ Hex」、「→ ASCII」按钮即可。In the ASCII Hex Converter: Type or paste your input above, then click "→ Hex", "→ ASCII".
能转换中文等 Unicode 字符吗？Can it convert Chinese or other Unicode characters?
不能。本页每个字符对应一个字节，只支持码位 0–255（ASCII 和 Latin-1）；输入中文等字符会提示错误。需要完整 Unicode 时，请使用 UTF-8 编码工具。No. Each character maps to one byte here, so only code points 0–255 (ASCII and Latin-1) are supported, and Chinese or other characters show an error. For full Unicode, use a UTF-8 encoding tool.
支持哪些十六进制写法？Which hex formats are accepted?
空格、逗号或冒号分隔的字节（48 69）、连写（4869）、带 0x 前缀（0x48 0x69 或 0x4869）以及 \x48\x69。每个字节必须是 2 位；数字个数为奇数时会报错并提示补 0，不会猜测。Bytes separated by spaces, commas or colons (48 69), run together (4869), with 0x prefixes (0x48 0x69 or 0x4869), and \x48\x69. Every byte needs two digits; an odd number of digits is reported as an error (add a leading 0) instead of being guessed.
编码和加密有什么区别？Is encoding the same as encryption?
编码（如 Base64、URL 编码）可直接还原，不提供保密性；加密需要密钥。「ASCII ↔ 十六进制」的处理全部在本地完成。No. Encoding (Base64, URL…) is reversible by anyone; encryption needs a key. The ASCII Hex Converter works fully offline in your browser.
