The European currency “Euro” (€) is represented by a symbol of somewhat dubious design, but it’s an important currency and (La)TeX users need to typeset it. When the currency first appeared, typesetting it was a serious problem for (La)TeX users; things are easier now (most fonts have some way of providing a Euro sign), but this answer provides a summary of methods “just in case”.
Note that the Commission of the European Community at first deemed that the Euro symbol should always be set in a sans-serif font; fortunately, this eccentric ruling has now been rescinded, and one may apply best typesetting efforts to making it appear at least slightly “respectable” (typographically).
The TS1-encoded TC fonts provided as part of the EC font
distribution provide Euro glyphs. The fonts are called Text Companion
(TC) fonts, and offer the same range
of faces as do the EC fonts themselves. The
textcomp package provides a \texteuro command for
accessing the symbol, which selects a symbol to match the surrounding
text. The design of the symbol in the TC fonts is not
universally loved…
Nevertheless, use the TC font version of the symbol if you are
producing documents using Knuth’s Computer Modern Fonts.
The each of the latin9 and latin10 input encoding
definitions for the inputenc package has a euro character
defined (character position 164, occupied in other ISO Latin
character sets by the “currency symbol” ¤, which
ordinary people seldom see except in character-set listings…).
The TC encoding file offers the command \texteuro for the
character; that command is (probably) only available from the
textcomp package.
Use of the TC encoding character may therefore made via
\texteuro or via the Latin-9 or Latin-10 character in ordinary
text.
Note that there is a Microsoft code page position (128), too, and that has been added to inputenc tables for CP1252 and CP1257. (There’s another position in CP858, which has it in place of “dotless i” in CP850; the standardisation of these things remains within Microsoft, so one can never tell what will come next…)
Outline fonts which contain nothing but Euro symbols are available
(free) from
Adobe —
the file is packaged as a Windows self-extracting
executable, but it may be decoded as a zip format archive
on other operating systems.
The euro bundle contains metrics, dvips map
files, and macros (for Plain TeX and LaTeX), for using these
fonts in documents. LaTeX users will find two packages in the
bundle: eurosans only offers the sans-serif version (to
conform with the obsolete ruling about sans-serif-only symbols; the
package provides the
command \euro), whereas europs matches the Euro symbol
with the surrounding text (providing the command \EUR). To use
either package
with the latin9 encoding, you need to define \texteuro
as an alias for the euro command the package defines.
The Adobe fonts are probably the best bet for use in non-Computer Modern environments. They are apparently designed to fit with Adobe Times, Helvetica and Courier, but can probably fit with a wider range of modern fonts.
The eurofont package provides a compendious analysis of the “problem of the euro symbol” in its documentation, and offers macros for configuring the source of the glyphs to be used; however, it seems rather large for everyday use.
The euro-ce bundle is a rather pleasing MetaFont-only design providing Euro symbols in a number of shapes. The file euro-ce.tex, in the distribution, offers hints as to how a Plain TeX user might make use of the fonts.
Euro symbols are found in several other places, which we list here for completeness.
The marvosym font contains a Euro symbol (in a number of typographic styles), among many other good things; the font is available in both Adobe Type 1 and TrueType formats.
Other MetaFont-based bundles containing Euro symbols are to be found in china2e (whose primary aim is Chinese dates and suchlike matters) and the eurosym fonts.
