I've tried to use getCategoryPages function in the category plugin. The recursive: true option works for Wikipedia in English but not for Wikipedia in French. See https://observablehq.com/d/9bf92e81eef871c0

good catch! I can try to look at supporting this, using the i18n plugin. Thank you - can you make a github issue?

made an issue here - https://github.com/spencermountain/wtf_wikipedia/issues/576
