How to know which of my fonts do or don’t support certain glyphs?

I have a long list of glyphs with various Unicode points across several Unicode blocks that I need to represent in a monospaced form (which mean with a single font). How I can know which glyph the font does not support in that list?

I tried Microsoft Word, Open Office, Notepad++ and some others, but even ᴡindows® Notepad tries to substitute unknown characters from glyphs in other fonts instead of using the replacement character directly. Sometimes it even substitute characters whereas they exist in the font

Opening a font editor and checking Unicode points one by one would definitely takes hours.
Below is the text I need to display properly

Answer

Today I learnt about a new tool, which “was made just for your question”. It was published in 2011 but I am sharing it here, less than one hour after I tested it:

Hope this helps, it is an .exe so will probably need Windows.
