Checkbox and Font

Dear Sir or Madame

I have two Problems... I wanted to copy text from a wordfile to a confluence page. But in the confluence page it seems that the fonts are different. But in the Wordfile all text has the same font... Can i change the font on a confluence page?

The second problem/question is:

I used tasks as a checkbox. But now i wanted to create a list with checkboxes. But if i create a list and want to add a checkbox ([]) then the checkbox shows up and the list disappears... Does it gives something to fix this? Or is this deliberately?

Thanks in Advance and best Regards,
