Since the April 2018 release, LaTeX considers UTF-8 as default input encoding Thus calling \usepackage[utf8]{inputenc} at the start is no longer required. If a file has a different encoding than UTF-8, the proper encoding should, of course, be declared. The utf8x add-on, together with the ucs package, used to be needed for some special application or, ...

That is a packaging error in miktex. That happens sometimes. In such cases go to https://github.com/MiKTeX/miktex-packaging/issues and report the issue (if it hasn't been done yet by someone else). I added an issue: https://github.com/MiKTeX/miktex-packaging/issues/159 As a work-around until miktex corrects this: Get hycolor.dtx from ctan https://ctan....

This will depend solely on what project you are referring to. Different projects are hosted on different platforms, so where you file bugs and feature requests will depend. Usually a project is hosted in only one platform (hosting in two doesn't make much sense and is a maintenance nightmare, unless one of them is just a mirror). For example The LaTeX ...

Searching this site for other astronomical icons, I have immediately finded this great answer https://tex.stackexchange.com/a/483433/204509. One can use the same technique for the planets: use some random image off the internet and include it as image. With http://cdn30.us1.fansshare.com/image/cartoonplanet/vector-cartoon-planet-icons-579074540.jpg one gets ...

You did not provide an example of a missing +, a more reasonable test file would be \documentclass{article} \usepackage{newtxtext,newtxmath} \usepackage{pslatex} \begin{document} $a+b$ \end{document} Do not load pslatex and in general you should delete most of the package lines, as they are repeating and conflicting. Only use a package if you know you ...

Here is how to do it with package leftidx and, dor the negated version, stackinset from stackengine: \documentclass{article} \usepackage{leftidx} \usepackage{stackengine, graphicx} \newcommand{\divides}[2]{\leftidx{^{#1}}{\Big\vert}{_{#2}}} \newcommand{\ndivides}[2]{\leftidx{^{#1}}{\nBigvert}{_{#2}}} \newcommand{\nBigvert}{\stackMath\mathord{\stackinset{l}...

While using LaTeX various packages are used. In case the package is not available then it is downloaded from the net on the fly and installed. pgfcore.sty is one such package. You need to install the package. The easiest way to do that is from the Start Menu->All Programs->MikTEX 2.9->Maintenance (Admin)->Package Manager (Admin) and search for the package ...

The short answer is that you can't retrospectively change options for already loaded packages (see here: Applying options to already loaded package), but if you design your class file carefully then you can probably make hooks for you to latch on to in each case. Using your example: \NeedsTeXFormat{LaTeX2e} \ProvidesPackage{test}[2014/08/21 Example package] ...

It's ⅇ U+2147 (ⅇ in HTML) so should be available in in any font that has double struck italic lower case. So any font used with unicode-math or for pdftex for example the stix and stix2 packages will make it available. Actually I don't see it in the stix2 package which is surprising, with unicode-math it is \documentclass{article} \...

I have found on this link a very nice speedometer too. I made a few small changes to associate it with my initial question. \documentclass[border=1cm]{standalone} \usepackage{newtxtext} \usepackage{tikz} \usetikzlibrary{decorations.text} \begin{document} \begin{tikzpicture}[font=\small] % Static part \draw[draw=white,fill=red,thick] (0:2) -- (0:3.5) arc(0:...
