letter t looks like +

[dwelle]

Above, which is a+p and which is atp? Answer is: I don't recall.

[thorn0]

People really write the t this way, don't they? What problem, exactly, does this create in practice?
Besides, + should normally have spaces on both sides.

[dwelle]

In practice it makes it pretty much impossible to know whether it's a t or a +.

Even if from context you can eventually decipher it, it's not a good UX:

Above readers may actually presume you've made a typo.

[thorn0]

It's always clear from the context IMHO. Is the fact that the Latin letter O and Cyrillic O look the same a bad UX?

[thorn0]

I found a real-world example where this can be a problem. Formulas like x = t + 1

I don't imagine it being a problem since you don't mix Cyrillic and Latin much?

Exactly. Same with +. You normally don't put it in the middle of a word like a letter.

This is an interesting issue! Can I take it up? :)

[anumithaapollo12]

As a user of Excalidraw I have found it difficult to differentiate the two. I would love it if it is modified for better UX. I have attempted in fixing it using FontLab. Let me know what you guys think :)

[dwelle]

@anumithaapollo12 thanks for helping out! We could also shorten the horizontal line so the vertical one is much taller (I kinda made the vertical one too tall in relation to the other characters):

How I write a lowercase t:

@dwelle I thought that it would still look similar. I get what just heightening the length looks like.
I've tried a couple more iterations based on your inputs. My personal favourite is the width shortened with left protrude, this way no harm done to the height and we get the looks of lower-case t. Let me know what you think!

@anumithaapollo12 Would be good to see these variants in context (in words and in formulas). It's difficult to say anything when they're in isolation.

Agreed. In particular, I'd like to try out the last two variants:

We need it some playground :)

[j-f1]

I think something like this (with a pronounced hook) would make the difference really clear.

For example, here is f from Virgil flipped vertically:

[anumithaapollo12]

@thorn0 @dwelle I'll use it in context to get a clearer picture of the letter!

[ellinor-rapp]

made the + a bit smaller and added a "hook" to the t to clarify

@dwelle Here are examples of the last two variants. My personal choice, the second one as it significantly looks like t.
Lemme know what you think!

Length heightened and width shortened

Width shortened and left protrude
