@helltux Here you go.
This plugin seems to be in working order.
Post reactions would be a nice plugin 🙂
@fiag Please let me know, how critical is the need for a pinyin slug, instead of %-encoded?
For example, https://nodebb.org.cn/topic/121/nodebb官方使用说明-建议大家提问前仔细阅读 to https://nodebb.org/topic/121/guan-fang-shi-yong-shuo-ing-jian-yi-da-jia-ti-wen-qian-zi-xi-yue-du
Edit: Well, it's not escaped here, but in other places w/o unicode support...
Is there such a possibility? Can it be developed?
Yeah need to check the textarea value and make sure it only contains @username and nothing else.
