I'm making a rectangle in the console and I found an underscore and an overline that look good with minimal spacing, what I lack is a vertical symbol to finish the rectangle. It looks like this now and I'm using the default keyboard | symbol but it looks like this:
I'd like to find a symbol that has a very minimal or even non-existent gap, just vertically.

I want to use the → character with two // strokes through the arrow but cannot find the unicode value for it anywhere. Does this exist in unicode? If not, is there a way to recreate it?
There are six Unicode characters whose name matches a right arrow with a double stroke, making use of the regular expression: /right.*arrow.*double.*stroke/.
Only two characters appear to be relevant candidates:
⇻ U+21FB RIGHTWARDS ARROW WITH DOUBLE VERTICAL STROKE
⭼ U+2B7C RIGHTWARDS TRIANGLE-HEADED ARROW WITH DOUBLE HORIZONTAL STROKE
(* RIGHTWARDS TRIANGLE-HEADED ARROW WITH DOUBLE VERTICAL STROKE)
Notes:
The official Unicode name of U+2B7C was initially wrong, but a corrected name has been added later as an alias.
U+2B7C appears to be quite uncommon, no suitable font was available in the OS used for the screenshot. Still, it is possible to see what it should look like in the Miscellaneous Symbols and Arrows - Range: 2B00–2BFF PDF document:
I was not successful in finding what you were looking for (negative result). U+0219B is a "Rightwards Arrow with Stroke" and U+021FB "Rightwards Arrow with Double Vertical Stroke". If it exist, it would probably be called "Rightwards Arrow with Double Stroke". https://en.wikipedia.org/wiki/Arrow_(symbol)
The following Unicode sequences should describe your character, but unfortunately fonts are not helping.
→⃫ : \u2192\u20EB
⟶⃫ : \u27F6\u20EB
They are normal and long arrow, with the combining U+20EB: COMBINING LONG DOUBLE SOLIDUS OVERLAY (long double slash overlay). You may find a technical font which can display both in the expected way.
You may get something acceptable also with:
⎯⎯⎯⃫⟶ \u23AF\u23AF\u23AF\u20EB\u27F6 (using arrow extension line)
⎯⎯⃫⟶ \u23AF\u23AF\u20EB\u27F6
Depending on the environment, one of the two seem much better (on my computers).
So: you can express it (semantically) with Unicode, but standards fonts are not helping us. You should experiment with many symbols/mathematical fonts, to get an acceptable solution.
As alternative, you can build such image easily with SVG (and use a SVG as character image).
Are these findable? I've turned them myself because I could only find left and right. I want it to be the text of my buttons.
The closest match is probably:
PRESENTATION FORM FOR VERTICAL LEFT ANGLE BRACKET (U+FE3F): ︿
PRESENTATION FORM FOR VERTICAL RIGHT ANGLE BRACKET (U+FE40): ﹀
Technically, these are punctuation characters from the CJK compatibility block used for vertical writing systems. What you're really looking for is an arrow-like symbol.
Try using a special font, like FontAwesome. Check out chevron-up and chevron-down.
I have to agree with some other responder, though, that SVG or even a sprite image would be better. You can set the text to be the unicode characters and style the element to show the image, so that selecting it and copying would give you the text.
I'm trying to learn Auto Layout and playing around with various view combinations. I have various views containing other views, but the one I'm having trouble with is one that contains a label and a text field. They are set up like this:
There are several constraints set up on these, such as center Y alignment between the label, text field, and parent view, 0 leading edge for the label, and a hard coded value (12, but irrelevant) for the trailing edge of the text field. I had initially had it as a 0 trailing edge, aligning it with the parent container. However, the right edge of the text field seems to be cutting off and I have no idea why... I Started increasing the distance, thinking that may be there's a margin issue, but nothing seems to help!
Would love any input.
I would like to change (or hide entirely) the "bent arrow" character that appears in the Emacs fringe (both on the left and right hand side). I'm using Emacs 24 on a Mac, installed via homebrew. I find it to be visually distracting. A smaller character, like a center dot, might work well.
For context, this is an official description of the small bent arrows (from http://www.gnu.org/software/emacs/manual/html_node/emacs/Continuation-Lines.html):
Sometimes, a line of text in the buffer—a logical line—is too long to fit in the window, and Emacs displays it as two or more screen lines. This is called line wrapping or continuation, and the long logical line is called a continued line. On a graphical display, Emacs indicates line wrapping with small bent arrows in the left and right window fringes. On a text terminal, Emacs indicates line wrapping by displaying a ‘\’ character at the right margin.
The Emacs LineWrap Wiki page does not address my question.
The best information I've found so far is contained in this StackOverflow answer:
When word-wrap is set to nil in a text terminal (-nw) Emacs, the backslash character appears on the right margin.
When word-wrap is set to t in a text terminal Emacs, the backslash character is not shown. Setting visual-line-mode also sets word-wrap to true.
This does not apply when Emacs is running as a GUI window: the small bent arrow appears on the right margin regardless of the value of word-wrap.
Is hiding or changing the bent arrows possible? If not, an answer that says, more or less, "I've looked at X and concluded that it is impossible" is ok too.
Update: Although it is not a terrible work-around, changing the fringes is not what I'm looking for: I want to customize the "bent arrow" character or bitmap.
First, some quick context. From Emacs Fringe Bitmaps: "Fringe indicators are tiny icons displayed in the window fringe to indicate truncated or continued lines, buffer boundaries, etc."
You cannot replace the curly arrow with arbitrary text. According to lunaryorn's answer to "Is It Possible To Replace Fringe Bitmaps With Text in Emacs?":
No, it is not. Fringe “bitmaps” are really bitmaps, that is vectors of 0/1 bits, overlayed over the fringe. There is no way to directly render arbitrary unicode characters onto the fringe. [...] What you can do, is to render a unicode character into a 0/1 bitmap yourself.
Like it says, you can change the bitmap. Fringe Bitmaps contains a list of fringe bitmaps; left-curly-arrow and right-curly-arrow are the ones relevant for this question.
Here is what I drew up. Adjust to your liking. Put this in your Emacs init file.
(define-fringe-bitmap 'right-curly-arrow
[#b00000000
#b00000000
#b00000000
#b00000000
#b01110000
#b00010000
#b00010000
#b00000000])
(define-fringe-bitmap 'left-curly-arrow
[#b00000000
#b00001000
#b00001000
#b00001110
#b00000000
#b00000000
#b00000000
#b00000000])
More documentation is available at Customizing Bitmaps, including set-fringe-bitmap-face which "sets the face for the fringe. If face is nil, it selects the fringe face. The bitmap's face controls the color to draw it in".
use Microsoft Word to edit an equation with underbrace. The line is as follows:
\underbrace(ab+cdf-edf=9dc/ereat+asdfdgg-asfeefe-eafdgahty+atataeaattrat)
The problem is the symbol for underbrace is very flat, looking like a line with the downward pointing part too small to see. Is there a way to make it larger (e.g., is there a way to stretch the underbrace VERTICALLY)? The size of underbrace is set automatically in Latex and looks fine. But in Microsoft Word, the default just does not look especially when you have a long equation. I am not sure if there is a setting allowing you to change it. Many thanks! Gene
