that is very good.. 

i'll add a few things..
So in short, Segoe UI is the font.
Steps 4-7 can be skipped...
babelmap is brilliant.. though in this case, perhaps not that relevant, because the composite font in babelmap is I think a custom one rather than a standard windows one, and the font coverage option lists all fonts with that glyph, which is brilliant, but in this case we already have a list of fonts with the glyph, in that composite file. And more than that, the list in the composite file is more apt, because that's the list we want 'cos that's the list notepad is using
or, steps 4-6 can be skipped.
babelmap is great, I put it to use also for its font coverage option to see what fonts on my system had that aleph glyph.. but that composite file really shows me.. And I can check that aleph is in segoe even with character map
character map has a weakness that it stops at FFFF but my char is before that so it's ok for checking the existence of the glyph, given the font

yes, BabelMap has its own composite font at it cannot load windows composite font directly. I'm not sure if it is only a bug or a missing feature
(maybe I have to upgrade BableMap to the lastest version and try there)
note that the font needs to be copied outside c:\windows\fonts because babelMap has no access there
perhaps the best solution if you need routine identification of glyphs is to re-create GlobalUI font in BabelMap (which will be 1:1 with GlobalUI font in Windows) and use Load/Save buttons in BabelMap to keep it stored permanently

regarding your finding:
you say "Segoe UI is the font"
FYI I'm on Windows 7 machine and Seogoe UI doesn't have Aleph glyph yet
so here, Tahoma is the font
