In markdown, if a footnote has a consecutive paragraph, it starts the line with " " (four spaces). This is a formatting information that is easy to lose when translating.
So, for future texts, "~~~~" should be used instead, so that this information is much less-likely to get lost. Then I'll just replace it back to spaces before rendering the files.
Also, it is very desired to have a script to check, on original files, if there is any case of those consecutives paragraphs (any case of " " on the beginning of the line). If this is the case, the footnote and this cases count should be recorded, and then later, compared to the translated text. If the translation's count is less, it should be notified that there is formatting information that was lost.
Then I'll just go and fix it on Github.
