Mac PDF annotation font switched

[dryoshie 0]

I was in a middle of annotating a PDF document, and after entering an left pointing arrow (by using special character insertion from Ctrl+Command+Space), the font switched from the default type (that looks like arial) to a font that looks like Times New Roman. This did not happen when I've inserted other types of arrows or special characters in the past. I've tried closing Evernote and re-opening, and tried inserting other special characters, but the font is now stuck at Times New Roman looking font. I'm not aware of any method to change the font, wondering how I can switch it back?
