Upside Down Text...Is ʇɥǝɹǝ ɐu ndsᴉpǝ-poʍu ɟnuɔʇᴉou¿

Question

For example,

Geovanny M.F.

1) Backwards->Reversing text
.F.M ynnavoeG

2) Flip Upside Down->Flipping text
פǝoʌɐuuʎ W˙Ⅎ˙

3) Mirrored->Both effects!
˙Ⅎ˙W ʎuuɐʌoǝפ

For doing this, there are upside-down characters using conversion:

Z⅄XꤵꓥꓵꓕSꓤÒꓒONꟽ⅂ꓘᒋIΗ⅁ℲƎꓷↃꓭꓯ
zʎxʍʌnʇsɹbdouɯןʞſ̣ᴉɥɓɟǝpɔqɐ
068᠘9૬ҺƐᘔl¡¿؛˙‘‚„⅋

As you can see they are quite limited when you need to use other ones.

Is there a flipping function? How to output cases 2 & 3 without conversion?
Maybe rotate a character 90, 180 or 270 degrees?

Not html, css & js!

Thanks!

Answer 1

Since it does not serve any practical purpose, I doubt you'd find a language which provides a built-in function or library which helps you to flip text, especially when we are talking about console programming and not GUI.

That said, it should not be too hard to write a function which takes a string, and return the flipped string. All we have to do is map the original characters to their flipped counterparts, and either iterate through the string and build the new flipped string, or to replace the original string characters using regex.

The problem here is that the flipped characters, or some of them at least, are unicode, which may cause some problems related to locales.

It's not what you asked for, but i couldn't resist:

Answer 3

Hatsy Rei There are really several applications in real life. Here, some of them:

Answer 4

Hatsy Rei I know it was three questions in one:

1) Flipped text
2) Mirrored text
3) Rotated text

It would be nice to have a built-in function in any language for learning & testing purposes. Anyway, I'm gonna try to take a glance at some algorithms created for that and search for any library out there. Maybe a finding might emerge!!!

Answer 5

Hatsey Rei One interesting finding. I will check it. Thanks!

Answer 6

Speaking of the devil =^=
I hope what I found here could be of help to your objective.

Answer 7

You're welcome 😊
I'm sure you can write a code for second case 😋

Answer 8

(1/2) Let's take the classic one & most modern used example:

0) original: AMBULANCE
1) reversed: ECNALUBMA
2) flippedV: ∀Wq∩˥∀NƆƎ
3) mirrored: ƎƆN∀˥∩qW∀
4) flippedH: EƆ A U MA (As you can see there are 3 missing characters. So, see image below for better comprenhension!)

Now, we have the 4th case which it is in reality the text written in front of ambulance cars. That is to say, the text is flipped horizontally (flippedH).

Answer 9

(2/2)
So, I was wrong regarding 3rd option. Although, it combines reversing effect & vertical flipping effect (flippedV), it is NOT the right 'mirrored' effect used in ambulance cars. Uhmm, maybe we have to give it another name 'cause the right 'mirrored effect' is the "flippedH" (4th case).

Cépagrave In any case, your code reproduces one of the cases required (the 3rd one). Well done!

Things are now crystal-clear and this finding helps me a lot.

In clonclusion, I still need to get a solution for 2nd case!!!

Geovanny Martínez Forero Thanks for the link! Those are some good examples, but I think my stance holds, that the applications are not wide enough to earn us a built-in upsidedown(). Maybe I'm unaware of a Python module which does that (?).

Answer 11

Cépagrave Thanks to your code I realized sth. So, I will provide explanation & link if possible...🙂👍🏻

wow interesting find...

Hello, I have even created one upside down text tools, you can be used to joke or humor https://codebeautify.org/upside-down-text
