It was originally written by Jonathan Kew and is distributed under the X11 free software license. Initially developed for Mac OS X only, it is now available for all major platforms. It natively supports Unicode and the input file is assumed to be in UTF-8 encoding by default. XeTeX can use any fonts installed in the operating system without configuring TeX font metrics , and can make direct use of advanced typographic features of OpenType , AAT and Graphite technologies such as alternative glyphs and swashes , optional or historic ligatures , and variable font weights. Support for OpenType local typographic conventions locl tag is also present. XeTeX even allows raw OpenType feature tags to be passed to the font. Microtypography is also supported.

If so, then this article is for you: a non-technical background to explain the many variations of TeX-based software—what they mean and why they exist. Those new to STM publishing, or considering it as a career, may be surprised to learn that typesetting software whose origins date back some 40 years is still in widespread use by technical authors—and forms a critical component of many modern publishing workflows through services such as Overleaf. It is a common, though understandable, misconception that the use of TeX is restricted to scientific and technical disciplines; specifically, the typesetting of complex mathematics. Whilst it finds most users in those domains, TeX-based software is widely used for the production of non-mathematical content—because of its high quality of output and incredible versatility. Or, if you are interested in cooking, how about producing a recipe booklet? The American historian Daniel J. Boorstin once noted that:. I decide I have to solve the problem myself. The quote above is from page of Digital Typography by Donald E. Knuth is a brilliant computer scientist and whilst developing TeX he, and his colleagues, designed new and sophisticated algorithms to solve some very complex typesetting problems: including automatic line breaking , hyphenation and, of course, mathematical typesetting.

What is XeLaTeX doing? Have you checked our knowledge base? When Knuth wrote xelatex original version of TeX he provided it with the features and capabilities that he thought were xelatex to meet the needs of sophisticated text and mathematical typesetting based on the technology environment of that time—including processing power and memory of computers, font technologies and output devices, xelatex.

The corresponding LaTeX compiler on Overleaf is called xelatex. You can also use LuaLaTeX to run the same code. Different elements in a L a T e X document are formatted with different fonts; for example, in a verbatim environment the text is displayed using a typewriter style. Different font styles can be set for each context:. In the previous example three different fonts are used, the next lines determine the elements that will use this fonts:.

There are a large number of fonts installed on Overleaf which you can use in your project, most easily via fontspec. The following examples show the use of fonts included on Overleaf's servers, such as Google Noto, together with fonts that you need to upload from Google Fonts.

The LaTeX story goes back all the way to when Donald Knuth first understood the need for a high quality typesetting program. It's a remarkable testament to the quality of LaTeX that the system he conceived back then is still the best tool for the job today, although many useful additions have been made in the decades since. Latex with a normal capitalisation and pronunciation is a type of rubber! The ancestor of all of these is of course the original TeX program by Knuth. This takes a document in plain text and transforms it into a beautifully typeset document. Knuth was quite particular about typesetting and the attention to detail in TeX is clear. An example TeX document might look something like this:. Notice how the combinations of letters 'fi', 'fj', and 'ff' in the example words run together in a pleasant way, and how the mathematics symbols are well spaced. On a larger scale, TeX does a very good job of breaking lines in the appropriate places to created well justified text, with hyphenations where appropriate.

During the s Knuth decided to freeze active development of TeX because he wanted to ensure the long-term stability of his software: he decided that no new features would be added to TeX. And that is precisely what LaTeX is: it is a very large collection of complex and sophisticated macros designed to help you typeset books, journal papers and so forth.

Of course, because TeX is controlled by a programming language there is always the possibility of making mistakes—bugs in your TeX file which TeX cannot understand or simply do not give the results you were expecting.

This article explains how to typeset Chinese documents on Overleaf. See this article to learn how to change the compiler in Overleaf. The ctexart document class part of the ctex package bundle which implements common Chinese typesetting practices.

There are a large number of fonts installed on Overleaf which you can use in your project, most easily via fontspec. Those updates take place every few years with the latest being The TeX tuneup of as reported in the TeX journal TUGboat —the next tuneup is scheduled for ! Boorstin once noted that:. Each TeX engine program understands hundreds of so-called primitive commands. In the default operating mode the xdv output is piped directly to the driver without producing any user-visible intermediate files. Have you checked our knowledge base? This enormous collection of software is managed and updated by leading members of the TeX community and culminates in yearly releases of a distribution called TeX Live —which will also contain the latest stable releases of TeX engines for each supported platform Windows, Linux etc. XeTeX is also supported by LyX since version 2. Those new versions of TeX not only provide additional features e. Knuth is a brilliant computer scientist and whilst developing TeX he, and his colleagues, designed new and sophisticated algorithms to solve some very complex typesetting problems: including automatic line breaking , hyphenation and, of course, mathematical typesetting. Your community of LaTeX users will value the suite of features Overleaf provides to manage their LaTeX projects—from uploading files and graphics through to sharing project links that enable teams to work together on the same paper. We have mentioned that each TeX engine supports a particular set of low-level commands called primitives—but this is not the full story. After uploading the font-family files into Overleaf project folders we can configure them for use via fontspec.
