# Cannot build PDF on Editorial Manager

I have a TeX manuscript I would like to upload through the "Editorial Manager" platform.

However, I keep getting errors like this when the platform tries to build the manuscript :

I uploaded a zip folder containing these files :

The JounalPics folder contains the figures all in .png

I wrote the manuscript using KILE and it compiles correctly. I get the compilation errors when uploading to Editorial Manager.

What did I do wrong ? And how can I fix it ?

Edit :

Here is the log file .

• What is the "Editorial Manager"? It is possible few or no others know what this is. – jon Oct 21 '16 at 19:03
• You have, at line 311, It is important to mention that α represnts the links’ hardness. It should be It is important to mention that $\alpha$ represents the links’ hardness. (fix also the typo). I believe you get the same error on all TeX distributions, the only difference is that on your system you disregarded it. – egreg Oct 21 '16 at 19:37
• @egreg I suspect that the OP believes that by using UTF-8 encoded files all their UTF8 symbols would show up on the produced PDF file. You are right in pointing out that's a mistake, at least as PDFLaTeX is concerned. Should we recommend using XeLaTeX or LuaLaTeX instead? As for the OP's system, it is likely that KILE executes PDFLaTeX in nonstop mode, so the error is ignored and the PDF produced simply omits the α. – errekak Oct 21 '16 at 19:52
• sorry I scrolled over the log too quickly I expected errors to be at the end but you made tex continue after the error, ! Package inputenc Error: Unicode char α (U+3B1) is in your dropbox – David Carlisle Oct 21 '16 at 19:58
• user1885868: better follow egreg's advice and use LaTeX commands for your symbols, at least in projects you mean to send through your platform: I don't know if they allow you to choose engines, as ShareLaTeX or Overleaf do; so better stick to the basic functionality of PDFLaTeX, which should be upwards compatible with "modern" TeXes. – errekak Oct 21 '16 at 20:04

The error message is

! Package inputenc Error: Unicode char α (U+3B1)
(inputenc)                not set up for use with LaTeX.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.
...

l.311 It is important to mention that α

Type  I <command> <return>  to replace it with another command,
or  <return>  to continue without it.


This means that at line 311 of your TeX file you have

It is important to mention that α represnts the links’ hardness.


which should be

It is important to mention that $\alpha$ represents the links’ hardness.


The same error is probably present in the log file you get on your system. Always check for errors after a LaTeX run, every front-end will tell you if there has been any.
