How do you write Munkre's topology T? [duplicate]

In James Munkres' classic topology textbook, he writes a topology T using a typeface I am unfamiliar with.

I tried looking it up using detexify and checking commonly used character sets but the closest I could find was a capital fraktur I.

• Hi, could you please post an image of how the letter looks like? – yo' Mar 19 '15 at 8:57
• Instead of linking, you could make a screenshot, clip the image to show just a few symbols and post it here. The pdf file you linked to is quite large. – Johannes_B Mar 19 '15 at 9:02
• That looks like \mathcal or some script T. – Johannes_B Mar 19 '15 at 9:03
• @Johannes_B I have updated my post. Sorry for the inconvenience. – Echan Mar 19 '15 at 9:08
• I would simply dupe that to What are all the font styles I can use in math mode? You can pick one from the very very good answer. Most likely, you want eulervm. – Johannes_B Mar 19 '15 at 9:08
