I'm trying to use non-ascii characters via hyperref's pdftitle option. I've read a similar question, but its solution isn't working for me. I'm working on Overleaf and when I download the PDF, a new window opens up with the location where the file will be saved. But the suggested name for the document is "Matem_tica" instead of "Matemática".
I've failed trying all the following alternatives:
\usepackage[unicode]{hyperref}\hypersetup{...,unicode=true,...}\hypersetup{...,pdfencoding=pdfdoc,...}\hypersetup{...,pdfencoding=unicode,...}\hypersetup{...,pdfencoding=auto,...}
Here is my document:
\documentclass{article}
\usepackage{amsfonts}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage[brazil]{babel}
\usepackage[sorting=none]{biblatex}
\usepackage{bm}
\usepackage{cancel}
\usepackage{epigraph}
\usepackage{float}
\usepackage[T1]{fontenc}
\usepackage[top=2cm, bottom=2.5cm, left=2.5cm, right=2.5cm]{geometry}
\usepackage{graphicx}
\usepackage{hhline}
\usepackage{hyperref}
\usepackage{indentfirst}
\usepackage[utf8]{inputenc}
\usepackage{mathabx}
\usepackage[framemethod=TikZ]{mdframed}
\usepackage{setspace}
\usepackage{tabularx}
\usepackage{xcolor}
\usepackage{csquotes}
\addbibresource{Referencias.bib}
\hypersetup{
colorlinks = true,
pdftitle = {Matemática}
}
\begin{document}
Hello!
\end{document}
Any help is appreciated!

Matemáticalisted as the Title in the PDF Property known as Description, when using Adobe Reader to open the file. – Steven B. Segletes Dec 29 '21 at 02:21
