When Chinese and English text are mixed, characters placed too closely together can cause reading difficulties. This tool uses Unicode character recognition technology to automatically insert standard spaces between Chinese characters and English letters, numbers, or punctuation. For example, it turns "Python编程" into "Python 编程", significantly improving text readability.
Q: Is it necessary to add spaces between Chinese and English text?
Yes. According to standard Chinese typography guidelines, spaces should be inserted in mixed Chinese and English text to improve readability.
Q: Will this tool change the original punctuation types?
No. This tool only adds spaces and does not alter the original full-width or half-width punctuation attributes.
We recommend processing plain text. The presence of HTML or Markdown tags may affect recognition accuracy. Please do not re-process text that has already been correctly formatted.
Typical input/output example:
Input: "学习AI技术3.0版本"
Output: "学习 AI 技术 3.0 版本"
We also recommend using this tool to optimize code comments, such as changing "#定义变量" to "# 定义变量".
