I used these to generate a Greek text font in normal +and bold weights, and also in italic and typewriter styles. + +The characters are mapped to the intuitive Roman alphabet equivalents, as +shown in Table~\ref{gr-trans}, with the use of some ligatures to handle Greek +letters traditionally represented by two Roman letters. These mappings are +{\bf not} everywhere the same as Silvio Levy's; in particular, note that he +uses `{\tt H}' to represent `{\grbf Y}'\footnote{The {\tt\bs grbf} font has +been used in all the in-text examples in this paper} (which is intuitive as a +capital, but not in lower-case [`{\tt h}'$\not\simeq$`{\grbf y}']) --- I feel +that my transliteration here makes the ``English'' Greek more readable, since +most of it tends to be in lower-case. (Incidentally, I originally started +with more ligatures, for example, `{\tt ks}' and `{\tt rh}' for `{\grbf x}' +and `{\grbf r}' respectively; the latter caused a minor disaster with the +Greek for `I start' ({\grbf arh\'izw}) which has to be input as `{\tt +arh\bs'izw}'!) + +Since I was interested only in Modern (Demotic) Greek, which adopted the +``one-accent'' system in 1982, I made no special provision for accents: in +particular, there is no simple way of generating breathing marks. I just use +the normal \LaTeX\ {\tt\bs'} before the accented letter: of course, this puts +the accent on capital letters in the wrong place ({\grbf \'Y} whereas it +should be {\grbf\'{}Y}), but one doesn't always need to accent capitals, +and \verb|\'{}| works when necessary. I recognize that using this form of +accenting precludes any attempt by \TeX\ to hyphenate the Greek words, but I'm +pretty clueless on {\em where\/} to hyphenate Greek in general! Some time, I +ought to get around to making `{\tt;}' into a sentence-ending punctuation mark +(since Greek uses it where English uses `{\tt?}'), and perhaps provide a +raised dot for the Greek semi-colon; at present, all punctuation marks are in +the conventional (Roman) positions, without transliteration, so you type a +`{\tt;}' to get the Greek question mark. + +\begin{table}[tbp] + \begin{center} + \begin{tabular}{cc@{\hspace{1cm}}cc} + Greek & Characters & Greek & Characters\\ + Letter & Typed & Letter & Typed\\ + \exmp A & \exmp a\\ + \exmp B & \exmp b\\ + \exmp G & \exmp g\\ + \exmp D & \exmp d\\ + \exmp E & \exmp e\\ + \exmp Z & \exmp z\\ + \exmp Y & \exmp y\\ + \grbf TH & \tt TH \rm or \tt Th & \exmp{th}\\ + \exmp I & \exmp i\\ + \exmp K & \exmp k\\ + \exmp L & \exmp l\\ + \exmp M & \exmp m\\ + \exmp N & \exmp n\\ + \exmp X & \exmp x\\ + \exmp O & \exmp o\\ + \exmp P & \exmp p\\ + \exmp R & \exmp r\\ + \exmp S & \exmp s\\ + & & \grbf \s & \tt\bs s\\ + \exmp T & \exmp t\\ + \exmp U & \exmp u\\ + \grbf PH & \tt PH \rm or \tt Ph & \exmp{ph}\\ + \exmp H & \exmp h\\ + \grbf PS & \tt PS \rm or \tt Ps & \exmp{ps}\\ + \exmp W & \exmp w + \end{tabular} + \end{center} + \caption{Transliteration from Keyboard Input to Greek}\label{gr-trans} +\end{table} + + +To facilitate the use of these fonts, I have designed a \LaTeX\ style file +option {\tt GREEK.STY}, which ought to be usable with any normal \LaTeX\ +style; at present, it is {\bf not} suitable for \SLiTeX. The commands {\tt\bs +gr, \bs grbf, \bs grit} and {\tt\bs grtt} are defined, and will automatically +track any \LaTeX\ size changing command ({\it i.e.}\ {\tt\bs Large} will +invoke a 14pt {\tt\bs rm} font in a 10pt document style, and then selecting +{\tt\bs grbf} will select the corresponding 14pt Greek bold font). Whenever a +Greek font definition is in force, the macro {\tt\bs s} is used to generate +the variant of lower-case {\tt\bs sigma} required at the ends of words. +(Silvio Levy's font takes care of all this automatically, however, I'm pretty +sure that my LN03 printer driver would fail if I needed more than 188 +characters from his Greek fonts, because each \TeX\ font needs to be mapped to +a single LN03 internal font, which has a maximum capacity of two 94-character +``chunks'' in the GL and GR terminology of ANSI X-3.64.) + +In the last few days I've been getting my hands dirtier with \MF, and have +changed the programs for a number of the characters; this was necessary +because they still exhibited that they were originally ``tuned'' for maths +setting. The characters changed are as follows:\begin{itemize} + \item The lower-case \verb|\alpha| was too wide and also extended right up + to the right-hand edge of the bounding box; this has been shrunk by some + judicious tweaking of points defining the pen stroke. + \item The characters \verb|\iota| and \verb|\mu| also came right up to + their right-hand sides; they have simply been redefined in a box one $u$ + wider. + \item The character \verb|\nu| had a vertical left stroke; this has been + curved and the serif (if any) blended in. + \item The character \verb|\lambda| was too wide: fine for denoting + wavelength and the like, but not very pretty in text; its width has been + shrunk by one $u$. + \item The character \verb|\kappa| is fine for maths, but not the form + ordinarily found in Greek text; what is wanted is something like the + \verb|\varkappa| provided by $\cal AMS$\TeX. My first thought was to + pirate that character from \verb|YSYMBOL.MF| (which we have) but of course + that's for the old MF-in-SAIL; I have written something in \MF84 which + approximates that character (please don't look too closely at the awful + code!) +\end{itemize} + +There is considerable scope for further work:\begin{itemize} + \item As mentioned above, because the Greek character definitions were + stolen from the maths fonts, spacing of some other characters is not yet + perfect; furthermore, the actual form of some other characters (notably + {\grbf z} and {\grbf x}) is not that normally expected in Greek text. + Eventually, I shall have to tweek them myself, or steal the appropriate + bits of Levy's fonts. (As mentioned above, I feel that use of his full + 256-character font would cause problems at this site.) + \item To make {\tt GREEK.STY} work with \SLiTeX\ as well, I shall have to + re-write {\tt SFONTS.TEX} to use a font size changing strategy akin to + that used by {\tt LFONTS.TEX}, this will also permit the use of {\tt + CYRILLIC.STY} (which we have also modified to track automatically \LaTeX\ + size changes) with \SLiTeX; quite frankly, I could never understand why + {\tt SFONTS.TEX} preloads all those fonts, when load-on-demand would seem + much more useful for the contexts in which \SLiTeX\ is used. + \item I haven't made any ``guillemets'' style quotation marks. +\end{itemize} + +Finally, an example; I don't know whether Silvio Levy asked the copyright +holder's permission to reproduce his example from Kazantzakis' ``Symposium'', +but I haven't! I have, however, followed modern usage of the one-accent +system. (I have also corrected what I presume to be a ``typo''; it may be, of +course, that Kazantzakis actually wrote what was printed in Levy's article, +but I feel that {\grit m' \'ezwsan} [``encircled me''] makes more sense when +referring to lightning than {\grit m' \'exwsan} [``evicted me''] --- +my {\grit Meg\'alo ep\'itomo lexik\'on ty\s\ Ellynik\'y\s\ gl\'wssa\s\/} +[{\it ca.}~1500{\sl pp}.] doesn't suggest any other sensible meaning for this +verb!) + +\def\bodytext{Ty stigm\'y to\'uty ni\'wthw p\'oso bar\'u 'nai to must\'yrio +ty\s\ xomol\'ogysy\s.
