Two days ago https://norcal.social/@superball asked about generating smart quotes on Linux. I never got to understand 
what they meant with 'smart quotes', but I answered with a reference to the US intl with dead keys keyboard layout. I 
have been using it for ages. This allowed me to write proper Spanish with a US layout and it just mimicked my experience 
when learning to type with a Olivetti Lexicon 80.

I knew for a long while that I gloat, yes, gloat, about being able to write 'weird' letters, but it seems like I never 
really wrote them all. So today I sat down to waste, yes, waste a couple of hours, as in more than two, compiling the 
following table:

glyph | name           | letters                                                  | key combo

The biggest surprises about it are:

* Overdot is the most ~~used~~ writable diacritic, even when 5 of the letters use a different diacritic.
* Underdot and caron get more than I expected.
* Only one letter with horn? Was it worth it? Maybe I don't know how to use it?
* Ogonoek is the best diacritic name. A shame is so underused :)
* If it wasn't for the overdot, `x` would be the single letter that can't be combined.
* Best symbol? I'm partial to `ř` because it's used to represent a Czech sound that is also present in the West
  North West part of my country, one ocean and one Equator apart. See 
  [https://www.youtube.com/watch?v=uDpVPj49R8w](a Brittish linguist) and, wow, 
  [https://www.youtube.com/watch?v=9cZSKnfeigI](a Cordobese comedian).
* But also `ẋ` and `ơ` for their different uniqueness.
  
Let me tell you about that last video. The guy is from Córdoba, from Cruz del Eje, so he has a mix of Cordobese accent
but the ř sound from Traslasierra ('behind the mountains', referencing the Sierras Grandes) and La Rioja. Riojan people 
have another accent.

Of course, these are not all diacritics (see
[https://en.wikipedia.org/wiki/Diacritic](diacritics on the Wikipedia)), and probably not all the possible combinations. 
Not to mention that they can be accumulated; see both glyphs noted with [^1], but also 
[https://en.wikipedia.org/w/index.php?title=Zalgo_text](Zalgo text).

Finally, diacritics are not the only thing you can write with this layout. These symbols are also writable
without combining:

¡¹²³¤£€¼½¾‘’¥×÷
äåé®™þüúíóö«»
áßðëïœø¶°
æ·©¢ñµ±ç¿

and `^` combined with digits writes them superscripted:

¹²³⁴⁵⁶⁷⁸⁹⁰

Definitely a very versatile layout. If you want to fully explore your keyboard layout, install `tastenbrett`[^18] and 
take a look.

Ah! And smart quotes are not actual glyphs but a feature (I completely forgot about it because I always deactivate them):

[https://en.wikipedia.org/w/index.php?title=Quotation_marks_in_English#Smart_quotes](Smart quotes on the Wikipedia).

[^1]: With `v`.

[^2]: I can't quite see the glyph[^3], so I have to trust Python and `unicodedata.name()`.

[^3]: I'm getting old (almost 50!), presbyopia is hitting and these glasses are 1yo. Maybe it's also 
      time I succumb and raise the minimum font size from 8 to 10.

[^4]: These ones are weird. At least on my editor they 'glue' to the character on its left and it 
      becomes difficult to deal with.

[^5]: While typing these, I had to use `Space` to make them show in their isolated form. Fore this one 
      I had to press it twice. Dunno why.

[^6]: Not 'double dots'? This symbol is _used_ for both diaeresis (diæresis?) and umlauts[^8].

[^7]: With `w`.

[^8]: How come all these names don't have themselves in it?!?! "Ümlaut", there, I fixed it for you :)

[^9]: According to my editor and Python, these are both `LATIN SMALL LETTER A WITH RING ABOVE`.

[^10]: Notice how the diacritic applied is different to the one you're supposed to be pressing.

[^11]: Can't help myself; I pronounce these in French :)

[^12]: Notice that the diacritic is an overdot, but these letters 'naturally' have dots in them, so it _removes_ it.

[^13]: Not sure if you see the same as me; I see a dot to the _right_ of the `l` glyph. If this is the canonical 
       representation, in some ways [^10] applies.

[^14]: This modifier changes the letters in many different ways, and the result not always looks like an actual diacritic,
       but I included it for completeness.

[^15]: It doesn't show at all; maybe because of [^14]?

[^16]: These actually get an undercomma. [^17]

[^17]: I have the impression that this post has more footnotes than actual text :)

[^18]: Literally 'keysboard' in German; 'tasten', keys; 'brett', board.
