How can I tell whether the text in a PDF is actually a font and not an image of text?

Hello,

I downloaded a PDF and opened it in Reader DC. I wanted to capture a single character and copy it to Notepad or another text application, but the selection tool does not seem to allow normal selection. The cursor image in selection mode does not look like an "I", it looks like a "+". And it allows you to select the character, but only by drawing a boundary box around it.

First, I looked at the document properties, security settings tab. No security - selecting and copying is allowed.

I'm thinking that this means the text is actually an image of text and it can't be selected. How can I make sure this is the problem?

Note: the document contains characters from a non-Western alphabet, and I thought that might be the issue, but it won't even allow me to select/copy roman letters or English words.

Thanks!
