They have purposely disabled being able to select text (outside of the SVG graphics) by literally doing this in CSS:
* {
user-select: none;
}
The user-select: none; is intended for places where interaction with an element (e.g., drag and drop, clicking, sliding) is required and text selection should not occur. You might use it discretely on a HTML button.
Blanket banning of text selection is a habit I've seen with developers who live in a touchscreen-heavy bubble, and who feel that users have no reason to select text at all unless explicitly enabled by the developer.

There, I copied that quote from their website (by disabling the relevant CSS); one example of a totally valid reason for wanting to select text.
They're using SVG because support for these non-standard punctuation varies across browsers and OS's, so its safest to use an image.
Many sites presenting informational content about unicode content do the same, as they cannot presume the user will see the unicode symbols rendered natively in their browser.
