The first glyph is SUMMATION TOP (23B2 hex, 9138 decimal).

The second glyph is N-ARY CIRCLED DOT OPERATOR (2A00 hex, 10752 decimal)

They can be found in several different fonts. Cambria Math has both glyphs, and Summation Bottom, of course. Code 2000 and DejaVu Sans also have very many symbols.

File Format Info is a useful site to bookmark.

The following description of how I analysed the problem might be of interest.

I copied the two characters, which showed as black rectangles in the web browser, onto the clipboard and then pasted them into SC UniPad, which is a program available from the following webspaces.

http://www.sharmahd.com

http://www.unipad.org

This displayed the characters. Highlighting them and using Edit Convert A \u... produced the Unicode code point values.

I then went to the Unicode webspace.

http://www.unicode.org

Moving the mouse pointer over The Unicode Standard produced a cascaded menu and I clicked on Code Charts.

This displayed the following page.

http://www.unicode.org/charts/

Realizing that the two characters being considered are symbols, I clicked on Symbols and Punctuation and arrived at the following page.

http://www.unicode.org/charts/symbols.html

The page links to lots of pdf files. As it happens, the names of symbol blocks are displayed, not the code points, yet if one moves the mouse pointer over the name, the code point of the first character in the code chart is displayed. Thus one can find links named Miscellaneous Technical and Suppl. Math Operators.

The links lead respectively to the following pdf documents.

http://www.unicode.org/charts/PDF/U2300.pdf

http://www.unicode.org/charts/PDF/U2A00.pdf

Curiously, in http://www.unicode.org/charts/PDF/U2300.pdf the example glyph for U+23B2 is not compatible with the glyph shown in the description listing.
