Yep, the adapter is easy to build. The minitel character set also has some handy glyphs in it for graphics.
http://millevaches.hydraule.org/info/minitel/specs/ Here is some information on the character codes too.
But hey, you can type 'µ' with a single unmodified keystroke!
But I do agree, Azerty is not that good most of the time. Especially when it comes to programming.
Indeed, same on Apple's "French" keyboard layout, unless you select the "French (numeric)" one, in which case caps lock produces numbers. Also, ` is a dead key, as is ^ and ¨, which works with caps too, but there's no dead key for acute accent (é).
Other bits of trivia:
On macOS, the numeric keypad (if any) is always num-lock'd.
The Apple "French" layouts are vastly different from the PC ones (also available as "French - PC"), relying on visual symbolism for extra glyphs which makes them (sort of) easier to remember:
option-n is ~ (which turns out to be a dead key)
option-l is ¬, option-t is †
option-shift-l is |
option-( is { and option-shift-( is [
“smart” ‘quotes’ are on " and ' with option and option-shift
there are ligatures too: shiftable æ œ fi on option-a o and g
question and exclamation marks are reversed with option too: ! -> ¡ and ? -> ¿
option-d is ∂ PARTIAL DIFFERENTIAL, option-shift-s is ∑, option-m is µ, option-f is ƒ
now guess how you do: © ™ ®
£ gives # when option'd (even though there's a dedicated @+# key)
shift-- is underscore, option-- is en-dash, option-shift-- is em-dash
similarly, there's also (grouped per physical key: no mod, shift, option, shift+option):
< > ≤ ≥
= + ≠ ±
: / ÷ \http://chrisbertrand.net/fr/articles/clavier_fr_esp_maj.html
Special thought for the ù letter, which has its own key even though it's only used in one French word 'où' (ok, we use this word fairly often, but still).
That's a limitation on Windows (and macOS?). On Linux, CAPS LOCK + é = É ; etc.
More like US layout centric.
EVen the humble unix CLI is a straight pain on anything but a US keyboard, as things like / now require a modifier key.
Funny thing is that There is a variant of the US layout with the right alt being alt-gr, allowing most languages that use latin script to be typed.
