what is the character code for "Modifier Letter Low Right Arrow" symbol ?
Please help me out as i am not able to find it anywhere since 2 days. everywhere they have given the code for "Modifier Letter Low Left Arrow" which is 02FF but not the right arrow .
Thanks
"Modifier Letter Low Left Arrow" is a character in the Spacing Modifier Letters block. It has a specific usage in a phonetic system. I don't believe the counterpart "Modifier Letter Low Right Arrow" exist.

I am learning flutter in most of my UI tutorial they are using this type of color code
0xfffbb448
I need to know what type is it? Where I can find these color codes? Try to find on google but not able to find which type of color code is this.
The color code 0xFFfbb448 is how you define a hexadecimal color in flutter. It starts with 0x, then 2 digits that represents the opacity/transparency, and then the last 6 digits is the color code Hex #.
You can get the 6 digit color code # from many sources such as https://htmlcolorcodes.com/ or https://www.w3schools.com/colors/colors_picker.asp
You may also find the 2 digits transparency code from sources such as https://gist.github.com/lopspower/03fb1cc0ac9f32ef38f4
An example:
Colors.blue.withopacity(0.5) would be the same as Color(0x800000FF)
where 80 means 50% opacity, and #0000FF is Hex color code for blue
There are many sources out there and similar questions like the below link to find out more.

I am writing code that draws a simple line graph to the Console, and can use Unicode characters. I am looking for the best way to encode 45° angled lines into my graphs.
For instance, here's a 2x2 block of Unicode characters, representing a 45° angled line intersecting a vertical line:
│
│╲
In an ideal world, I'd like to find a set of Unicode characters which fits in the same 2x2 space and touches the edges in the same spots, but the diagonal line reaches all the way to the vertical one somehow.
The closest thing I've found is that you could replace the vertical line with ▕, like this, but then the vertical bar won't touch the edges in the same spots, so it won't cleanly fit the rest of the graph.
▕
▕╲
Any other ideas?
Different fonts draw "one eighth block" differently, so you just need to choose the font that better suits your needs, e.g.:
- Hack font
- Segoe UI
- MS Gothic
Other characters, that may be come in handy:
U+2595: ▕ (Right one eighth block)
U+258F: ▏ (Left one eighth block)
U+2571: ╱ (Light diagonal upper right to lower left)
U+2572: ╲ (Light diagonal upper left to lower right)
U+2573: ╳ (Light diagonal cross)
More drawing characters:
https://en.wikipedia.org/wiki/Box-drawing_character
one of these might work. The Font is the Symbola Font. The Hex column is the hex representation for the unicode font shown on the right.

I have some problems using Psychtoolbox Screen and Textwindow...
For my experiment I want to give an instruction at the beginning. I used something like this:
% Draw text in the middle of the screen in Courier in white
Screen('TextSize', window, 20);
Screen('TextFont', window, 'Courier');
DrawFormattedText(window, 'Hello World', 'center', 'center', white);
And the other basic Screen definitions.
The problem is: The text is not fully shown. I tried different sizes and set the Font to Times, but it is always the same - every letter is only displayed 3/4 (ca)...
What could be the problem?
Would be very nice if someone can give me a hint...
Thanks!
Can you describe what you mean by 'every letter is only displayed 3/4 (ca)"? The code you posted looks correct. For example, here is that code, with the addition of some set-up routines, and taking and saving a screenshot as "testImage.png", with the screen shot attached.
screenNum = max(Screen('Screens'));
window = Screen('OpenWindow', screenNum, 0);
white = WhiteIndex(window);
Screen('TextSize', window, 20);
Screen('TextFont', window, 'Courier');
DrawFormattedText(window, 'Hello World', 'center', 'center', white)
Screen('Flip', window);
imageArray = Screen('GetImage', window);
WaitSecs(3);
Screen('CloseAll');
imwrite(imageArray, 'testImage.png');
I found the problem... Just a dumb mistake in my long Code. I have set the Font and Size of Text earlier, and this interfered with this new text features. Nevertheless, thank you for your help!

I'm putting the finishing touches on a GUIDE (MATLAB) developed GUI. I wanted to add tooltip strings to help the user but I don't want to overwhelm the user. Here are some examples of tootip strings that I have so far:
These are tooltip strings for 4 radio buttons that I have in a radio-group panel.
Apply annotation to highlighted region of the selected electrode pair
Apply annotation to entire data range of selected electrode pair
Apply annotation to entire data-set of selected lead (6 electrode
pairs)
Apply annotation to entire data-set for both leads (12 electrode
pairs)
This is the tooltip string for a toolbar push button
Press to start annotating. Depending on selected mode, a highlight
tool or window will appear
Are these too long or are they an acceptable length? Currently they convey all the information that I need to convey to the user. If these are too long, what could I do to shorten them?
Bonus question: Is there a general short-hand that is used for these types of user "hints" or "tips"?
I find them a little too long and convoluted. I don't know all your buttons, but if you don't have a button to specify a subrange, I would not mention 'entire range' and just omit that. Same with 'apply annotation'.
Compare:
Apply annotation to highlighted region of the selected electrode pair.
to
Apply to highlighted region of selected pair.
Similarly:
Apply annotation to entire data-set of selected lead (6 electrode pairs)
to:
Apply to selected lead of 6 electrode pairs.
Also, if the button already says 'annotate', there is no need to repeat it.
Press to start annotating. Depending on selected mode, a highlight tool or window will appear
to:
Show highlight tool or window to annotate
What I do generally is to keep it to the main point and rather exclude info that make it too long. If a wall of text pops up, people quickly lose interest.
If your GUI has ways to undo what you did with a button press, a curious press to see what it does is also a good thing.

I'm currently working on my thesis, and one of the requirements is to put a dot just next to the page number (which is at the top right corner).
This is the code that I am using for the moment. It does everything that I want except for the dot...
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{} % sets both header and footer to nothing
\renewcommand{\headrulewidth}{0pt} %Deletes the horizontal bar
\fancyhead[R]{\thepage} %puts the page number to the right
Could someone help me with my problem ?
Thank you in advance.
Use something like \hspace to \thepage:
\fancyhead[R]{\thepage \hspace{1 mm} . } %adjust 1 mm to any value as needed
Just put the dot after the \thepage;
\documentclass{article}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\renewcommand{\headrulewidth}{0pt}
\fancyhead[R]{\thepage.}
\begin{document}
See the page number in the top-right corner.
\end{document}
The result:
