The Hands Have Eyes

Statement

Goal

Braille is a system for converting the letters of an alphabet to a series of raised "dots", enabling the visually impaired to read by touch rather than sight. Each character is composed of six "cells" numbered like so:

1 ○● 4
2 ●○ 5
3 ○● 6

Observe that individual cells can either be "on" (raised) or "off" (flat). The letters a through j are encoded as follows:

●○ ●○ ●● ●● ●○ ●● ●● ●○ ○● ○●
○○ ●○ ○○ ○● ○● ●○ ●● ●● ●○ ●●
○○ ○○ ○○ ○○ ○○ ○○ ○○ ○○ ○○ ○○

The letters k through t are the same, except that cell 3 is also raised. For this problem, we'll pretend that u through z are the same as a through f with cells 3 and 6 raised, but be advised that this deviates slightly from standard Braille.

Braille can encode far more than just letters, but for this problem we'll only need these two modifiers:

○○ ○●
○○ ○●
○● ●●

The first indicates "Shift" (capitalize the following letter), and the other means that the next letter should be treated as a number, with a through i interpreted as 1 to 9 and j as 0.
Naturally enough, six empty cells encode a space.

○○
○○
○○

‒‒‒‒‒‒‒‒‒‒

Given three lines of input containing a message encoded in Braille, output the decoded message.

Warning Languages designed only for ASCII characters may handle Unicode characters like ○ and ● by treating them as two or three consecutive characters.

Input

3 lines of Braille cells (○ and ●, with characters separated by a space) containing a message to be decoded

Output

the decoded message

Constraints

N <= 100, where N is the length of the decoded message

❌ Rejected the contribution. Comment: dbdr and dwarfie (and some others) warned you about unicode in the comments of another of your contributions which was approved. Since, players encountered problems with it, both because despite what you said some languages don't handle correctly such chars (or at least not simply), or because users don't know how to manage them (and 15 minutes is a little short to solve the puzzle + find how read unicode chars.), or because some browsers don't display them correctly. The characters used here are differents, but causes problems anyways, with JS (and perhaps others, I have not tested all the languages). This contribution could be interesting, but unicode will just make it really hard (or even impossible) to solve for many users, only to improve a bit the aesthetic for the others...

❌ Rejected the contribution. Comment: in js readline() doesn't read inputs correctly

I actually think this is ok for clash of code, although maybe only for fastest mode and not for shortest mode. One thing I would change though is to make the Braille cells (the circles) into characters that are typeable on the keyboard.

Why?

I know this problem statement looks huge, but the diagrams make it seem like far more reading than it actually is. It's only ~160 words and a cursory Google search says the average reading speed is 200-250 WPM. Please give your fellow CodinGamers (and yourself) a little more credit before commenting that it's too much reading for a Clash of Code puzzle.
