I want to obtain the following symbol for denoting the Siegel upper-half space. The picture is as follows:

I have checked the PDF document The comprehensive LATEX symbol list, but I could not find out what I want to look for.

I do not know what is the font type of this symbol, I guess it belongs to some German-Goth style. Anyway I am not sure.

Any suggestions are appreciated, and thanks in advance.

\mathfrak{H} and \mathfrak{I}? Looks like euler, https://i.stack.imgur.com/980yM.jpg – Troy Jul 27 '17 at 10:51
@Troy Yes, that's it. It requires \usepackage{amsfonts} or \usepackage{amssymb}. – egreg Jul 27 '17 at 10:53
@ Troy Thank you very much! That is exactly what I am looking for. – GL_n Jul 27 '17 at 11:00
