The text I posted was:

Via our friends at NASA AREN:

spruce sticks -- https://www.aircraftspruce.com/categories/building_materials/bm/menus/wp/spruce.html 

⅛ foam core -- https://www.amazon.com/24X36-White-Foam-Core-Backings/dp/B0073YEE8A 

I wonder if the 1/8 caused this? Weird character?

[namangupta01]

Yes 1/8 caused the problem because i tied to post without 1/8 and it was posted.

Indeed! Changing the 1/8 to just 1/8 instead of the fraction format didn't cause an error! Maybe we need some kind of encoding protection to filter posts for this kind of thing?
