[Tex/LaTex] Vietnamese babel: font consistency

Question

I am writing a document in English, but want my name written in Vietnamese. I am using babel and mathpazo. The problem is that when I switch font to Vietnamese as in this minimal example:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[vietnamese,german,english]{babel}
\usepackage[osf,sc]{mathpazo}
\usepackage{mathrsfs} 
\begin{document}
{\Large Vietnam}

\begin{otherlanguage}{vietnamese}
{\Large Việt Nam}
\end{otherlanguage}
\end{document}

the font is also switched from Palatino to… something else, see the output below.

Is there anyway to keep the Palatino font also for Vietnamese language? I am very grateful to your comments.

Answer 1

The text font defined by mathpazo is not available in T5 encoding (for Vietnamese). The Palatino clone in the TeX Gyre fonts is, so you can use it:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[vietnamese,german,english]{babel}

\usepackage{mathpazo} % for math fonts
\usepackage{tgpagella} % overrides the text fonts in mathpazo

\usepackage{mathrsfs}

\begin{document}
{\Large Vietnam}

\begin{otherlanguage}{vietnamese}
{\Large Việt Nam}
\end{otherlanguage}

\end{document}

No oldstyle figures, I'm afraid.
