I am using browserless/chrome with ChangeDetection.io to capture screenshots of a Japanese website.

The page contains Japanese text (Kanji), but the glyphs look like Simplified Chinese instead of Japanese. The characters are correct, but the font rendering appears Chinese-style.

I have already tried:

• Setting --lang=ja-JP
• Setting Accept-Language to ja-JP
• Setting LANG=ja_JP.UTF-8 and LC_ALL=ja_JP.UTF-8
• Installing Japanese fonts (IPAex)

However, the screenshots still render Kanji with Chinese-style glyphs.

How can I force Chrome in browserless to use Japanese fonts (JP glyph variants) instead of Chinese ones?

Is there a recommended way to configure fonts or locale properly inside the container?

Thank you.
