How can i type "x" with circumflex

[WladimirKazantz]

Hello

I would like to ask how can i type "x" with circumflex

i.e. a unitary vector.

I search on mathcad unimath font and I didn't find it.

[RichardJ]

Use an x with the combining diacritical mark for a circumflex (0302). Not all fints properly support this (the circumflex may not line up properly), but Mathcad Unimath does.

[WladimirKazantz]

Can you post a worksheet

I can't understand how to do this

[RichardJ]

Well, that's strange. I could swear it worked testerday with the Unimath font, but today I can only get it to work with the UnimatPrime font.

[WladimirKazantz]

I can combine characters only in a text mode

When I type in math mode the circumflex appears at the right of "x"

then when i type spacebar, everything is fine.

[WladimirKazantz]

Also,

How can i type space in a varriable??

[RichardJ]

Use a non-breaking space (character 00A0)

[wayne]

You can also enter special characters in a math (or variable) region using [ctrl][shift] K, to type a space or some thing else, maybe you can type the text for the circumflex that you got to work.

See help "Typing Reserved Keystrokes And Special Symbols In a Name"

[RichardJ]

Yes, you are right. A normal space seems to work. I could have sworn it had to be a non-breaking space..

[RichardJ]

Which version of Mathcad, and which font are you using?

[WladimirKazantz]

I use mathcad 15 and i use "times new roman"

but i try also sylfaen, mathcad unimath and arial

the best that i reached is with "Microsoft PhagsPa"

[RichardJ]

Like I said, not all fonts correctly support this. Apparently, these do, although I have not tried them:

Thanks a lot

I fixed it. I used "Arial unicode MS" and everything ok.

[mzeftel]

I just tested x circumflex with Segoe UI, and the combining characters, which you can search for in CharMap.exe work correctly in Mathcad 15.

It doesn't work for me. I can't understand why.

Any way.

I also try to type "k" with circumflex with "Arial unicode MS"

and the problem is that circumflex is typed almost on "k".

It is too low.

As I say, any way.

[RichardJ]

Fonts are designed for specific purposes, that do not necessarily include putting a circumflex over a k. I am certainly no expert on this, but I believe the font has to specifically support the combination, or it may not work properly.

At a minimum, it's a complicated mess. See here for more information:

[WladimirKazantz]

Ok, then.

I 'll not spend time for now to read it, I put it for later,but I would like to ask one more question.

If I am gonna work with LaTeX , will I face these problems?

[RichardJ]

My understanding is that the problem is with the font itself. Maybe it's possible for the software (in this case LaTeX) to have some way to handle this when it encouters a problem, maybe not. I really don't know enough to say whether that is even possible. You would have to try it.

[WladimirKazantz]

One more question.

How can I denote a tensor?

A letter with a double axe over it?

I can make my own font but there is a problem with the size and also I must spend a lot of time to make it.

[RichardJ]

Same answer, really. You need to find a font with the correct combining mark, that works with the letter you want to use.

[WladimirKazantz]

I guessed that this would be the answer but I tried many fonts, first of all these for which work the circumflex, but it didn't work for double axe. Is there any other suggestion because I really don't want to start learning Latex.

Thank you for your response.

[RichardJ]

Sorry, but I think at this point you have more experience with this than I do.

[wayne]

You can easily construct what ever you want using windows Private Character Editor (search windows help).

The problem is, you cannot access the font file, at least I can't, so you can only use the characters on that computer. You would need to make again on each computer.

If someone knows of a way to get that private character file, so you could share that file, then that would be a good solution. I hit a dead end.

[WladimirKazantz]

I tried it, to be clear I tried eudcedit.exe but when I used an already fixed character and I modified it, the character appears much smaller than the real one.

For example if I use "Times New Roman" with size 12 I must put my character on the size 20 to be almost the same, ok maybe this is not big problem but some times it is very annoying.

I don't know if there is the same problem with others editors. As it seems I have to try it.
