2020年5月25日 · Then go to bullets/Stars and select for example the white diamond WHITE DIAMOND Unicode: U+25C7, UTF-8: E2 97 87 you can use that symbol in word. By the way this example runs on Mojave. By the way this example runs on Mojave.

2018年10月20日 · Note that I don't want to use the unicode character as a "palette", I want each item plotted by geom_point() to be the same shape (color will indicate the relevant variable). Running . Sys.setenv(LANG = "en_US.UTF-8") and restarting R does not help. Wrapping the unicode in sprintf() also does not help.

2023年12月25日 · With geom_text() you'd have more control over used fonts (e.g. using Font Awesome for icons); and with 2 geom_text() layers, you could first draw solid (white) hearts and then add regular glyphs to add red outline.

The lower case \u escape prefix represents Unicode characters with 16-bit hex values. For 32-bit hex values use the upper case \U or a surrogate pair (two 16-bit values):

2012年3月9日 · Even names of symbols such as BLACK MEDIUM SQUARE or WHITE MEDIUM SQUARE are not meant to indicate that the corresponding character must be presented in black or white, respectively; rather, the use of black and white is generally just to contrast filled versus outline shapes, or a darker color fill versus a lighter color fill.

2019年2月26日 · I'd like to use Unicode shapes in ggplot2 geom_point() (specifically, arrows like ↘, Unicode "\u2198", or LaTeX \searrow), as in shape = "\u2198", that are not in the default font. In this unanswered post, @Laserhedvig commented "it seems that the problem lies in the font. Apparently, the base default fonts don't contain support for these ...

2021年6月6日 · Shapes take five types of values: An integer in [0,25] The name of the shape; A single character, to use that character as a plotting symbol. Hence it looks as if it is not possible to mix the types. Instead I would suggest to use unicode symbols for the other shapes too, e.g. "\u25CF" for a circle

2010年11月16日 · I need to decide whether to render geometric symbols in a web GUI (e.g. arrows and triangles for buttons, menus, etc.) as Unicode symbols (MUCH easier and color-independent) or GIF/PNG files (lots of

2017年3月4日 · Unicode defines glyphs, which is the code points and the shape of the characters, not the color. Some new fonts and font renderers have support for color emoji but generally font size, color, boldness, slantness cannot be controlled by Unicode –

2024年2月12日 · One lightweight option to achieve your desired result would be to use unicode shapes, i.e. "\u25d6" and "\u25d7" will give you a left/right half circle. Note however, that not all fonts support these symbols. Additionally, you can't mix unicode with the default shapes, so you have to use unicode symbols for the other shapes as well:
