An updated answer for Lion and above:
You can also type ⌘+^+Space to bring up the characters menu, then start typing to search, and search for place of interest, then press enter to start selecting them, then tab to the correct result, then enter again to insert it.
Sounds like a lot, but it can really be narrowed down to ⌘+^+Space, typing pla, and then ...
The "~" key is located between the "left shift" and "Z" keys on the international english keyboard.
Many users are used to have this key under the escape key (the US layout), and they (including me) use the KeyRemap4MacBook software to swap those keys.
KeyRemap4MacBook is now called Karabiner. Here is a screenshot of the configuration I'm using to ...
There are some important gotchas with the other solutions posted here.
For one, symbol and text substitution entries only work in Cocoa apps. If you want a truly system-wide solution that works in all applications, this is not an option.
Also, apps like KeyRemap4MacBook are great, but relying on them means you have to keep the app running in the background ...
Press Command ⌘+Control ⌃+Space.
Type lamda into the search bar. Pay attention to type lamda instead of lambda.
Your lamda should be there:
You might ask why it is spelt lamda not lambda.
According to the link provided by MJeffryes:
The use of the spelling lamda derives from ISO 10646. This does not
mean that it is more correct than lambda, merely ...
I also found it hard to find a straight answer for this, so I just went into System Preferences > Keyboard > Text and created a use symbol and text substitution option where when I type (cmd) it replaces it with the command symbol.
Font Book does in fact have a view that displays all glyphs provided by a font — just select Preview - Repertoire on the menu bar:
You can also get a preview of a font using Quick Look: select a font file (from /Library/Fonts) and press space.
Found it, my fault. I had recently defined a system-wide shortcut associating the symbol "•" to another string. Worst idea ever! As soon as a dot appeared, it was expanded to several characters, all replaced by dots, and so on. Since I usually use 1Password, I only hit the issue a few days after the fact.
Now there's something on the internet in case ...
This might be one of those that changes by language, but on a UK English keyboard [& from comments, also US English], there are 4 dashes available from the key to the right of 0, Minus.

— - Opt ⌥ Shift ⇧ (em dash)
_ - Shift ⇧ (underscore)
To complete the set, & from ...
If you can enter the ² and ³ once, you can put it in as a substitution in System Preferences, Language & Text -> Text.
Put something unique on the left side, like ^^2, then paste your symbol in on the right.

In Character Viewer, click the gear icon in the top-left, then select "Customize List".
In the dialog that appears, scroll to the bottom and check "Unicode" under the "Code Tables" branch.
You should see something like this if you click on the "Unicode" item that's now in the left-hand pane (with unicode hex values down the left-hand column):
What is your reason for not wanting to switch the entire keyboard binding to Greek? If your reason was just that switching by the menu is a bit cumbersome, then you could set up a keyboard shortcut instead, for very quick layout switching.
With this, it takes just three keystrokes to type a λ (or any other Greek letter). I frequently need to type isolated ...

It's there for me in Character Viewer (Emoji & Symbols, expanded version). It doesn't have a glyph, but if you double click it should be inserted.
Note that you may have to go to the gear wheel at top left and select Customize to add the Unicode category. The Unicode category is under Code Tables.
This is described by Apple:
I think this must be a bug in the system for suggesting emoji in Predictive Text. The mystery character is FE0F, Unicode Variation Selector-16, which is used to signal that the preceding character should have emoji instead of text presentation format.
Solutions / Workarounds:

To type a superscript character in an application that doesn't support superscript, you can use Character Viewer:

You'll find these under the Symbols > ① Digits list
Here they are for copy pasting:
Using the Character Viewer, search for "Prime". You can then click "Add to Favorites" for more convenient access.
In Mavericks, the following shortcut is helpful to bring up the character viewer:
Control + Command + Spacebar
Click the button in the top right corner to switch between the "Characters" window and "Character Viewer". Note: to get that ...
The "Character Accent Menu" settings can be adjusted under:
System preferences -> Keyboard -> Delay Until Repeat
If you reduce this time, it's the fastest way to insert any accents in my experience. Setting the initial key repeat rate is the same as setting the time for the character accent menu to appear. With this solution, there is no need to change to ...
These are U+fb01 and fb02, Latin Small Ligature Fl and Fi. They are in Unicode really only because they were contained in legacy 8 bit character sets like MacRoman, but should no longer be used for anything. In modern technology such ligatures are created by fonts on the basis of the underlying codes for the separate characters, which is what should aways ...
It's possible with CoreGraphics (CGEventPost), it's a C API (it doesn't work in a Cocoa-AppleScript), but it's possible to call an executable from an AppleScript.
Here is the method to create the executable with Xcode (Version 8.3.3):
You can do it yourself (you can download Xcode from the App Store), or ask a trusted person to create the executable.
To type this character, type ⌥+E, then ⇧+E. "É" is the character I get.

Press caps lock ⇪.
Press the é key (that's the 2 on a QWERTY).
Press caps lock ⇪ again.
But you need to make sure you're using the French layout, and not French - numeric (“Français - numérique”, French flag with “123” beneath it).
Otherwise, you're explicitly asking the system to use the caps lock key as a shift lock for the numbers bar ...
