Interesting work.

I believe you use a word processor to compose and then you cut and paste to submit the poem. However, that process can result in the strange characters you see because the site does not recognize non-ASCII characters.

You can edit the poem to remove these characters and then type in the proper ones (most often ' or " ).
When you compose your poems, hit 'save as' and save them as either ASCII Dos text or else ANSI Windows text. That will convert the poem to what this site reads.
