The beauty of LaTeX

There are several reasons why one should prefer LaTeX to a WYSIWYG word processor like Microsoft Word: portability, lightness, security are just a few of them (not to mention that LaTeX is free). There is still a further reason that definitely convinced me to abandon MS Word: you will never be able to produce professionally typeset and well-structured documents using most WYSIWYG word processors.
LaTeX is a free typesetting system that allows you to concentrate on content and forget about the layout: the software takes care of the actual typesetting, structuring and page formatting, producing documents of astonishing elegance.
The software I use to write in LaTeX on a Mac compiles documents in PDF format (but exporting to other formats such as RTF or HTML is also possible). It supports unicode and all the advanced typographic features of OpenType and AAT fonts, like Adobe Garamond Pro and Hoefler Text. It allows fine-tuned control on a number of typesetting options, although just using the default configuration results in documents with high typographic quality. In what follows I review some examples, comparing how fonts are rendered in MS Word and in LaTeX.

1. Kerning

Kerning is the process of selectively adjusting the spacing between letters pairs to improve the overall appearance of text. Examples of letter pairs that need kerning treatment are AV, AY, PA, and AT. These letter pairs often look awkward together, and need to either be moved closer together, or further apart manually. Professional typesetting systems and fonts allow fine-grained adjustments for such letter pairs.

2. Real small caps

Most word processors create fake small capitals by adjusting the size of capitals. Professional fonts contain different sets of glyphs for small capitals and full-size capitals that any serious typesetting system should be able to use in the appropriate context. In particular, real small capitals are more than resized versions of uppercase capitals: they have a relatively heavier stroke and are designed to be visually compatible with lowercase characters of the same typeface.

3. Common ligatures

A good typesetting programme should always use contextual intelligence and substitution tables to determine whether ligatures are needed. Common ligatures are essential to professionally typeset text.

4. Rare and ancient ligatures

LaTeX in conjunction with professional fonts gives the possibility to exploit the whole set of rare ligatures and decorations, that are automatically added to the text.

MS Word (text with no ligature):

LaTeX (text with rare and old-style ligatures):

5. Glyph variants

Expert fonts often include variants or alternate shapes for alphabetic characters and numbers. XeTeX with the fonstpec package offers the possibility to access and select variants on single characters or for a whole text block.

6. Line breaks, justification and hyphenation

Legibility results not only from a good selection of typefaces, but also from a correct distribution of characters and whitespace per line. To attain this goal, most WYSIWYG word processors use relatively dumb justification/hyphenation procedures (i.e. algorithms that establish the position for line breaks by processing text line by line). LaTeX uses an advanced algorithm, originally developed by Frank Liang in 1983 for his PhD dissertation, which considers paragraphs as `wholes´ in order to decide where to add line breaks. The algorithm uses language-specific patterns in order to decide the preferred position for hyphenation. The engine then selects line breaks so as to make paragraphs look as good as possible. Information that is taken into account for calculating optimal line breaks includes the number of consecutive lines ending with hyphens, word tightness on each line, the change of tightness between consecutive lines. Further development has enabled the LaTeX engine to allow certain characters to stick into the margin, thus generating an optically straight margin - i.e., a margin that looks straight without being geometrically so. LaTeX's hyphenation settings can be fine-tuned by expert users.

7. Getting expert fonts

XeTeX gives the best results with expert fonts such as those based on OpenType technology. Most of them can be purchased from digital foundries, but Mac OS comes bundled with a number of excellent fonts with expert features (e.g. Hoefler Text, Optima, Skia, Apple Chancery, Zapfino). More free OpenType fonts are available on the net. Check out for example the Gentium, Charis SIL and Doulos SIL fonts from SIL, Cardo by David J. Perry, the free fonts designed by Jos Buivenga (the creator of Fontin), or this amazing collection of professional quality fonts selected by Vitaly Friedman.

9. Technical notes

These examples were produced on a Powerbook G4 running Mac OS 10.3.9, with Microsoft Word v.X and TeXShop 1.35, the XeTeX engine with fontspec package, and using the following fonts: Adobe Garamond Pro (commercial font), Adobe Minion Pro (commercial font), Hoefler Text (font bundled with Mac OS X), Zapfino (font bundled with Mac OS X).
