"! Package inputenc Error: Unicode char Ṕ (U+1E54)"

Does anyone know me explain what this error means and how to fix it?












\item Sejam $E_{1}, \dots, E_{n}, \dots$ conjuntos mensuráveis e 
considere $E = \bigcup_{1}^{\infty}E_{j}$. Dado $\epsilon>0$, para 
cada $j$ escolhamos um aberto $O_{j}$ com $E_{j} \subset O_{j}$ e 
$\me(O_{j} - E_{j}) \leq \frac{\epsilon}{2^{j}}$. Temos que $O = 
\bigcup_{1}^{\infty}O_{j}$ é aberto, $E \subset O$ e $O-E \subset 
\bigcup_{1}^{\infty}(O_{j} - E_{j})$. Ṕelas propriedades (i) e (ii) da 
proposição \hyperlink{2}{1.1.5}, temos
$$\me(O-E) \leq \sum_{1}^{\infty}\me(O_{j} - E_{j}) \leq \epsilon.$$

    Done! The problem is in the line "Ṕelas propriedades (i) e (ii) da proposição \hyperlink{2}{1.1.5}, temos" – Corrêa Oct 12 '18 at 22:08

    Can you try to compile with LuaLaTeX (I work well for me)? After can you put this code \[\me(O-E) \leq \sum_{1}^{\infty}\me(O_{j} - E_{j}) \leq \epsilon.\] instead of $$...$$? – Sebastiano Oct 12 '18 at 22:20

    is Ṕ a common letter in Brazilian Portuguese? (we were wondering if this should be defined by default, but don't recall this coming up before, and practically we can't pre-define every possible Unicode accent combination,so need to make a judgement on which letters to pre-define and which leave for the user to define if needed) – David Carlisle Oct 13 '18 at 15:19

    Unrelated to the problem: It is unnecessary to load a package more than once, you can remove the second \usepackage{graphicx} from your preamble. – samcarter_is_at_topanswers.xyz Oct 13 '18 at 15:40

    This is just a problem caused by a typo. – BlackBird Oct 14 '18 at 22:49

You only show a small fraction of the error message. The full error message shows more context and how to fix it:

! Package inputenc Error: Unicode character Ṕ (U+1E54)
(inputenc)                not set up for use with LaTeX.

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

You may provide a definition with

As suggested, adding


to the end of your preamble fixes the problem.
