I am really sorry, I am not familiar with transifex at all. Translation to French is already complete…
Regarding your trouble, it is not clear indeed whether the system recognizes the difference of ‘%’. I did not know we can have two different ones…
I think best is that you drop a message to one of the project coordinator eldy or novalore (https://www.transifex.com/dolibarr-association/teams/32145/zh_CN/). They should have the relevant answers !
