I have trouble with setting up greek letters to be used in SI unit. I need to set up the microseconds unit for my measured value. However, any solution I found online straigh just failed on my end. This is my document preamble:
\documentclass[12pt,twoside,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[shorthands=off,czech]{babel}
\usepackage{csquotes}
\usepackage[style=iso-numeric]{biblatex}
\addbibresource{lab03.bib}
\usepackage{float}
\usepackage{lmodern}
\usepackage{graphicx}
\usepackage{attachfile}
\usepackage{subcaption}
\usepackage{cleveref}
\usepackage[document]{ragged2e}
\usepackage{textcomp}
\usepackage{gensymb}
\usepackage[shortlabels]{enumitem}
\usepackage{siunitx}
\sisetup{
detect-mode,
detect-family,
detect-inline-family=math,
group-separator={ },
group-minimum-digits={3},
output-decimal-marker={,}
}
\captionsetup[subfigure]{subrefformat=simple,labelformat=simple}
\renewcommand\thesubfigure{(\alph{subfigure})}
\title{Laboratorní úloha č.~2 \textemdash\ Výkonové polovodičové systémy\\ \large \emph{Měření na~napěťovém střídači}}
\author{Marek Poláček (POL0423)\\ VŠB \textendash\ Technická univerzita Ostrava\\ Fakulta elektrotechniky a~informatiky}
\date{\today}
And this is how the greek letter shows up:

Basically, \textmu inside \si{} displays μ as ţ. When I use \mu, it displays correct glyph, but slanted, which is wrong. I need the upright variant. Placing directly μ in the code makes thing even worse, it doesn't display at all. Tried using textgreek package, didn't help at all. I am running out of options here and I need to finish it as soon as possible.
Please, what am I doing wrong?
\micro\secondor\us. And it should be\SI{76,43}{\micro\second}(not with\numand\si). – egreg May 02 '20 at 17:01$$for better alternative, since it won't make any visual change. However, thanks for suggestion, might as well use in future – Polda18 May 02 '20 at 21:16\SI{1}{\micro}and it still turns up as 1ţ in the PDF. – Thomas Tiotto Oct 01 '22 at 09:36
