<div>
<div> </div>
<div>This is true, but I wonder why searching for accented characters works in my PDF viewer. Maybe evince recognizes these characters and is able to search for them or converts them. I don't believe dvips or dvipdfmx would (or should) do this.</div>

<div>together with an acute accent character (at position 19) which is typeset over it. You therefore can't find it by searching for 'é'. In addition,</div>
<div>you can't specify hyphenation for words with accents with CM.</div>
<div> </div>
<div>For this and other reasons, the EC (European Computer Modern) fonts were created, which do have single characters with accents. I suspect LaTeX is using them (or some other font with this feature) by default or because of some package or other that you're loading, but I have to pass on questions relating to LaTeX.</div>
<div> </div>
<div>Of course, there's no reason why you can't use the EC fonts together with eplain:</div>
<div>
<div>\font\rm=ecrm1000</div>
<div>
<div>\font\it=ecti1000</div>
<div>etc.</div>
<div> </div>
<div>Personally, I wouldn't bother changing the math fonts.</div>
<div> </div>
<div>If you want to see the characters of a font and their encodings (in octal and hexadecimal), you can run `tex testfont'. I've attached the output (with tables -- there are other options) for cmr10 and ecrm1000.</div>

<div style="font-family: Lucida Sans;">Hello again,<br/>
<br/>
TeXShop actually works with (and depends on) MacTeX.<br/>
When I type in LaTeX with TeXShop, the problem does not arise.<br/>
When I type in Plain TeX and eplain I use the appended file to avoid typing TeX accents (i.e. type é instead of \'e).<br/>
However even the code<br/>
<div style="margin-left: 40.0px;">\magnification 1200<br/>
th\'eorie<br/>
\end</div>
<br/>
Produces a pdf which is correct for viewing but fails finding the word "théorie".<br/>
I suspect it is an encoding issue, but have no idea of where to look.<br/>
I tried all the manipulations with postscript, dvi, ps2pdf, etc. Nothing works.<br/>
<br/>

</div>
<div>How about if you look at the PDF in your browser?</div>
<div> </div>
<div>At any rate, it would appear that it is not a TeX or eplain problem. I'm not familiar with TeXShop. I would try the following:</div>
<div> </div>
<div>If you're generating PDF directly, I would try the following:</div>
<div> </div>
<div>1. Generate a DVI file, i.e., by using TeX the "normal" way.</div>
<div> </div>
<div>2. Look at it with xdvi or YAP or some other DVI viewer.</div>
<div> </div>
<div>3. Convert the DVI to PostScript with dvips (dvips -o <ps-filename> <dvi-filename>).</div>
<div> </div>
<div>4. Look at the result with Ghostview (gv) or evince ("Document Viewer") or some other PostScript viewer. </div>
<div> </div>
<div>If that works, as I expect it would, you could try:</div>
<div> </div>
<div>5. Convert the PostScript to PDF with ps2pdf (ps2pdf <ps-filename>) and then check the result. You could try downloading evince, if you don't already have it.</div>
<div> </div>
<div>
<div>If the problem lies with TeXShop, you could try installing MacTeX: <a class="moz-txt-link-freetext" href="https://tug.org/mactex/index.html" target="_blank">https://tug.org/mactex/index.html</a></div>

<div>It would be helpful if you would supply an example and also explain exactly what version of TeX, etc., you're using; specifically how you are generating the PDF file. </div>
<div> </div>
<div>I don't know if this could be the problem, but I have occasionally had issues with things not working when using pdftex that do work with tex + dvips + ps2pdf. This applies, logically enough, to features specific to dvips. However, it might be worth a try, anyway.</div>
<div>
<div>
<div> </div>
<div>A typical cause of problems with accented letters not being printed is when using accented letters in the input with fonts with no corresponding glyphs. With a "normal" version of TeX and the CM fonts, you're on the safe side if you use control sequences, e.g., {\'a}, {\"a}, etc. It is possible to set up characters as being "active", but that may not be relevant here.</div>
<div> </div>
<div>Since CM doesn't contain accented characters as single glyphs, you will get characters plus an accent by using the control sequences. If you are using some other font that does define single characters with accents, you must use the correct characters in your input, corresponding to the encoding of the font. If you are using characters in the input that aren't assigned to characters in the current font, nothing will be printed.</div>

<div style="font-family: Lucida Sans;">Hello,<br/>
<br/>
I come across an unexpected issue with the pdf file of a book written with eplain. I turns out that accented letters are not recognized by the pdf. is there anything I can modify either in the source or in the pdf to make accents recognized?<br/>
Many thanks in advance for any help.<br/>
