Ogham is an old Irish script made by carving notches into stones. It fell out of use more than a millennium ago - but it's an interesting exception to a linguistics and computer-science rule that I'd never even realised existed. Let's talk about the Ogham Space Mark. Thanks to all the team at the British Museum!

Comments from Youtube

Ignideus : This video is gonna be hell to try and search for later

hey its me jop : Tom I thought we were done with these unicode disasters

Michael Name : Oh, i see. That's why they make all those "edge" phones. To properly display Ogham.

Gavers23 : Are you trying to crash our phones again?

Dagwoodland : The title translates to “Tom Scott and Ogam”.

vptes1 : And of course unicode/utf8 supports it...

┓┏ 凵 =╱⊿┌┬┐ : I don't think Chromecast supports the text in the title. It's rectangles with crosses in them

HugoH : Yes Tom, tell me about rectangle-rectangle-rectangle and rectangle-rectangle rectangle

Alexander F : Unicode really has to be considered one of the greatest accomplishments of the modern world. The fact that I can easily switch between English and 日本語 and expect virtually everyone who encounters those characters to see them rendered correctly is astounding. People under maybe 15 have probably never encountered a webpage full of broken unreadable encodings for an unsupported text standard.

GoDzM4TT3O : Title says “Tom scott” and “Ogham”. Thank me later. Also yes, if you search “Tom scott and Ogham”, this video will come up.

T2SF : I'd really like to see academic papers folded like accordions to write Ogham.

klop422 : Zero-width space is also nice to stop programs from turning your emoticons into emoji

vptes1 : Oh crap in js /\s/.test(' ') == true. Tom is right!! :P

Mister Apple : 2:14 Where are the options for I Don't Know and Can You Repeat the Question?

Zekke64Bit : Hmm. Yes. I can totally understand and see what the title is.

Nico Jones Gödel : Hi Tom, I'm Catalonian, and I thought this might interest you. In Catalonia we have the double L (meravella - miracle) and the "L geminada" (lit: doubled L), which we write with a dot (l·l) as in Paral·lel. (and it's pronounced like the italian ll). The interesting thing is that the dot · IS actually a breaking space: if a word doesn't fit on the line, it can be separated, whereas a double-L can never be separated: Me-ra-ve-lla, but a double L can: Pa-ral-lel. And, in that case, you don't write the dot and use the hyphen instead... but there can never be a confusion! isn't that neat?

GreyJolly : But was that something that I might not have known? Hey Vsauce, Tom here, but what is something?

Mark : Oh great, now American hipsters are going to be getting tattoos of Ogham now because they are 1/28th Irish. Cheers Tom.

_Bob McCoy : *Captcha has joined the chat*

Lúcás Ó Daimhín : It's nice to hear you talking about Irish history. I feel it's often underappreciated so thank you.

Number_055 : And of course, unicode supports this 15,000 year old script.

EastWood : This language remind me of that alien language from movie *Arrival* Except space, that language have absence of time.

Oxi : Omg, I thought it was a kebab in the thumbnail :D

s6th : More language! Thank you so much, Tom!

saber7ooth : Boxes and less boxes

TruelyJohn64 : Wish I could read the title...

Rian Young : I used to have a necklace with my name carved in Ogham. Growing up in Ireland...

Pranav Bhasin : Clicked on the thumbnail because I thought the video was going to be about Chocolate cake


ydmf2 : Looks like gyro meat...

Lawrence Calablaster : Tom, ogham is one of my favourite things. Thank you for making this video.

spikeman4pres : Can we get more Tom Scott at the British Museum?

Luwe Luwerson : Hell yeah, Ireland. I remember learning about these in primary school and writing words/our names on one.

Ryan Patterson : What about underlined Roman text? I believe that works identically. A continuous underline is drawn through "empty" space characters and when the text wraps to a new line, the underline is terminated and continued with the text on the following line.

h w a s a - e n t h u s i a s t : I love getting educated through your channel :^)

Adam Engberg : My favourite space character is Buzz Lightyear,

Mr. Vegana : When you want to swear in Roblox

scorpioninpink : Give it back to Ireland! The British museum is full of looted treasures!

The Makeshift Engineer Thomas weaver : Hey Tom if you read this I love your vids and love science. Thanks for keeping me occupied when I'm bored😊

TravenTalks : btw, title translates to "Tom Scott and Ogham" Well, technically the second part is "Ogam", but I think that's just an alternate spelling.

Chaitanya Singh : Your pin Also, the commentor who's reading this' name

Robert Hohan : I very much enjoy the transition to 4K / UHD / 2160p! Wasn't sure you'd keep it, but I hope it's permanent from now onwards.

Scriptminer : Really interesting, as always! (I suppose that's kinda the point...)

Rob B : Yes/No/Maybe I don't know. Can you repeat the question? You're not the boss of me now.

Alan Martin : I saw the thumbnail and thought you were standing next to a donor kebab.

Hydrocarbon : Me: Hey you should watch Tom’s new video Friend: Really?, What’s it called? Me: Oh uhm...yeaahh about that..

Jacob Albano : Ogham has gifted us with a fun thing to try in Javascript: try evaluating this in your console: 1 +  1 The answer may surprise you!
