Make Hugo Count Korean Words Correctly in Page Summaries (hasCJKLanguage, isCJKLanguage)

Configure Hugo so that Korean word counts are handled correctly in page summaries, preventing summaries from becoming too long.
Tags:

On Hugo post list pages, the beginning of an article is displayed as a summary limited to a specific number of words, usually 70 words. However, this word count is calculated based on languages such as English by default, so Korean and other CJK text is not counted correctly, and summaries may be displayed too long.

Configure in the Settings File

To count Korean characters correctly and display short summaries, set hasCJKLanguage to true in the settings file as follows.

For config.toml

hasCJKLanguage = true

For config.yaml

hasCJKLanguage: true

With this, Hugo’s internal .Summary and .WordCount work correctly for Korean, and shorter summary text is displayed.

Configure Per Page

If you want to configure it for each page, set isCJKLanguage to true in the front matter as follows.
