When using AnQiCMS for content display, many friends may have a question: why when the text content is continuous Chinese, the template ofwordwrapThe filter seems unable to automatically wrap at the specified length like it does with English? This often leads to unexpected extensions in the page layout, affecting aesthetics and readability.
To understand this phenomenon, we first need to have a deep understanding ofwordwrapthe working principle of the filter in the AnQiCMS template engine, as well as the characteristics of Chinese text itself.
Deep understandingwordwrapThe working principle of the filter
AnQiCMS template system provides a series of practical filters for data processing, wherewordwrapit is a tool used to control text line breaks. According to the official documentation,wordwrapThe core function of the filter is to automatically wrap long text at specified lengths.
However, its key working mechanism isBased on spaces to identify 'words' and perform line breaks.In other words, this filter will treat a continuous character sequence in the text as a "wordIf a character sequence does not contain spaces, it is treated as an indivisible whole, even if it is very long, the filter will not break the line within it.
For example, if we process English text{{ "hello world"|wordwrap:2 }}Using this filter, it will be normally wrappedhelloandworlddue to spaces between words.
the specificity of Chinese textwordwrapand its limitations.
This leads to the problems encountered when processing Chinese text.Different from languages such as English and German, Chinese text is a continuous stream of characters, and spaces are usually not used between words to indicate word boundaries.For example, there is no space between each Chinese character when writing "AnQi Content Management System
Therefore, whenwordwrapThe filter treats a continuous Chinese text without spaces as an indivisible "giant word" when it receives it.In this case, no matter how long the line break parameter you set is, the filter cannot perform line breaks between the Chinese characters inside it because it cannot find any separators (spaces) between 'words', and therefore cannot achieve the expected automatic line break effect.This makes the filter seem at a loss when dealing with continuous Chinese text.
Solution and Recommendations
Since we understandwordwrapThe working principle of the filter and the characteristics of Chinese text, then we have a direction to solve this problem.通常，我们不建议通过后端修改原始内容来强制换行，因为这会增加数据处理的复杂性，且可能对内容本身的语义和 SEO 产生不必要的副作用。The most elegant and recommended solution is to control it through CSS styles on the front-end.
Method 1: Front-end CSS Style Control (recommended)
For modern web design, the solution to this kind of text wrapping problem is to use CSS properties to control. The following two CSS properties can effectively solve the forced line break problem for continuous Chinese text:
word-break: break-all;This property will force the browser to break lines between any characters, regardless of whether they are within a word. It is very effective for Chinese text and can ensure that long strings of text will not overflow their containers.overflow-wrap: break-word;(or)word-wrap: break-word;)This property allows the browser to break long words within words (for Chinese, it is between characters) to prevent overflow.word-wrapIs the old property name,overflow-wrapIt is a standardized new attribute name, the function is basically the same, it is recommended to use it at the same time to achieve better browser compatibility.
Application example:Assuming your text content is in one<p>Tag or some<div>In the container, you can apply CSS styles like this:
.your-text-container {
word-break: break-all;
overflow-wrap: break-word; /* 兼容旧浏览器，也可只用 overflow-wrap */
}
Or, if you want all article content to wrap automatically, you can set it for related elements in the global styles:
article p, .content-body {
word-break: break-all;
overflow-wrap: break-word;
}
Through this method, you can achieve intelligent line breaks for continuous Chinese text without modifying the original text data and backend logic, ensuring the neatness of the page layout and the comfort of user reading.
方法二：后端预处理（谨慎使用）
Although not recommended, in extremely rare specific scenarios, if you really need to preprocess content on the backend to force line breaks, consider the following ideas:
Insert a zero-width space (
​or\u200B)： Zero-width space is a special Unicode character, which is invisible in display, but is recognized as a breakable position by browsers.You can insert this character between fixed numbers of Chinese characters before storing text content into a database or before outputting in a template.For example, 'Anqi Content Management System' is processed as 'Anqi content management system'.This requires writing additional processing functions, such as traversing the string and inserting zero-width spaces every N characters.
Important reminder:This method may change the original content and may introduce invisible characters, which are not convenient for management and maintenance, and may increase the storage space of the database, and may perform poorly in some old or non-standard web browsers.It should be avoided to useand prefer front-end CSS solutions.
Summary
when the CMS users encounterwordwrapFiltering is essential when the filter fails to automatically wrap continuous Chinese text. Understanding its line break mechanism based on spaces is crucial due to the special nature of Chinese text.wordwrapFilter cannot find a newline point in a Chinese sequence without spaces. The most recommended and effective solution is to use front-end CSS.word-breakandoverflow-wrapThis property handles. It provides a more flexible, standardized, and easier-to-maintain text layout, ensuring that your website content is presented with a good reading experience on various devices.
Common Questions and Answers (FAQ)
1.word-break: break-all;andoverflow-wrap: break-word;What is the difference between these two CSS properties? Which one should I use?
word-break: break-all;Forces a newline between any characters, even in the middle of an English word. This means it ensures that text does not overflow more 'aggressively.' And.overflow-wrap: break-word;(Formerly known as)word-wrap: break-word;）Then it will attempt to wrap lines within English words, but will prioritize at word boundaries.For continuous Chinese text, both effects are usually similar, and both can force line breaks between characters.In most cases, it is recommended to use these two properties together to achieve **compatibility and effects**.
2. Why mywordwrapFilter does not work on English text?
IfwordwrapIt's very likely that your English text does not contain any spaces, which is why the filter does not work.wordwrapThe filter identifies words based on spaces. For example, if you have a long English wordsupercalifragilisticexpialidociousand there are no spaces in the middle,wordwrapThe filter will still treat it as a whole and will not break lines within it. In this case, it is also necessary to rely on the front-end CSS propertiesword-break: break-all;oroverflow-wrap: break-word;to force line breaks between characters.
3. If I force insert zero-width spaces for line breaks in the backend content, will it affect the website's SEO?
Theoretically, zero-width space (Zero Width Space,}]}​In HTML, it is usually considered a normal line break by search engines and will not directly result in content being penalized or affect keyword recognition.However, too many unnatural zero-width spaces may cause search engines to misjudge the quality of your content, or in some extremely rare cases, affect their understanding of the page text structure.It is more important that this method increases the difficulty of content maintenance, and may bring invisible character problems when copying and pasting visually.Therefore, from the perspective of SEO and content maintenance, it is still strongly recommended to solve the text wrapping problem through front-end CSS styles, rather than modifying the content itself on the backend.
