文本水印是一种将标识信息隐藏在文本中的技术，肉眼通常无法察觉，但可以通过特定方法提取出来。它利用Unicode字符集中的特殊字符（如零宽字符）或其他不可见字符，将水印信息嵌入到原始文本中，不影响文本的可读性和显示效果。
使用本工具给文本加水印非常简单：
加了水印的文本看起来与原文完全相同，但实际上已经包含了隐藏的标识信息。
文本水印主要有以下几个重要作用：
本工具使用Unicode字符集中的零宽字符（如零宽空格、零宽连接符等）来实现水印功能。这些字符在显示时不占用空间，肉眼无法看见，但实际存在于文本中。通过特定算法将水印文字转换为这些不可见字符的序列，并将它们插入到原文本的字符之间。
解码时，工具会提取出这些特殊字符并还原为原始的水印文字，同时分离出未添加水印的原始文本内容。
虽然文本水印技术能够有效保护您的内容，但也有一些限制：
为获得最佳效果，建议在重要文档中测试水印的可靠性。
Text watermarking is a technique that hides identifying information within text, typically invisible to the naked eye but extractable through specific methods. It utilizes special characters from the Unicode character set (such as zero-width characters) or other invisible characters to embed watermark information into the original text without affecting its readability or display.
Using this tool to watermark your text is very simple:
The watermarked text looks identical to the original, but actually contains hidden identifying information.
Text watermarking has several important functions:
This tool uses zero-width characters from the Unicode character set (such as zero-width spaces, zero-width joiners, etc.) to implement watermarking functionality. These characters do not occupy space when displayed, are invisible to the naked eye, but actually exist within the text. Through a specific algorithm, the watermark text is converted into a sequence of these invisible characters and inserted between the characters of the original text.
When decoding, the tool extracts these special characters and restores them to the original watermark text, while separating out the original text content without the watermark.
Although text watermarking technology can effectively protect your content, it also has some limitations:
For best results, it is recommended to test the reliability of the watermark in important documents.
