Appearance of Greek µ with siunitx is regular font with Gentium but italic with XCharter – why?

Question

I'm trying to select a serif font for my thesis, and have narrowed down my choices to two (probably!) – Gentium and XCharter. I like both, but the latter puts the Greek µ for 'micro' in italics when using macros from the siunitx package – which I don't like. The only difference between the two preambles is the font loaded (MWE shown with gentium loaded and XCharter commented out; just reverse these to see the difference).

\documentclass[a4paper,12pt]{scrreprt}

\usepackage[greek, UKenglish]{babel}
\usepackage{siunitx}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{gentium}
% \usepackage{XCharter}
\usepackage[libertine,bigdelims,vvarbb]{newtxmath}
\usepackage[cal=boondoxo]{mathalfa}

\sisetup{detect-all}      % Uses current font for units ({siunitx})
\setlength{\parindent}{0cm} 

\begin{document}
{\textbf{Gentium}} \\
% {\textbf{XCharter}} \\
Homogenate was drawn off into a \SI{2}{\ml} tube, and \SI{400}{\ul} chloroform was added to it.
\end{document}

Why does XCharter behave differently, and is there a workaround?

Er, don't understand the question! What do you mean by 'escape all the brackets'? — Mark Birtwistle, Oct 25 '14 at 12:34
Ah, I do now see that strange characters have appeared before and after my code! Not sure what happened there, it was a simple copy and past from my .tex file. Anyway, duly edited – thanks @Sverre for pointing it out. — Mark Birtwistle, Oct 25 '14 at 12:40
I'm not sure it's in italics, it's the design of the available symbol. — Manuel, Oct 25 '14 at 12:53

Care to add some explanation? – Chris Chudzicki Oct 25 '14 at 18:14
My penultimate comment contains the necessary information and adding them again -- would be quite repetitive wouldn't it? – jlk Oct 25 '14 at 18:22

I think it wouldn't. – Manuel Oct 25 '14 at 18:25
I think that's a good explanation: http://tex.stackexchange.com/a/135125/25683 – jlk Oct 25 '14 at 18:42
But you could also load the upmu form the upgreek-package, \usepackage{upgreek} \sisetup{ text-micro={$\upmu$}, } – jlk Oct 25 '14 at 18:46
