Thích Nhất Hạnh in LaTeX tufte-book class

Question

I am very new to LaTeX and am wanting to use the OVERLEAF.com template found here: https://www.overleaf.com/latex/templates/book-design-inspired-by-edward-tufte/gcfbtdjfqdjh

I am using MiKTeX.
I am trying to include this name in my book: Thích Nhất Hạnh

but have not yet been successful.

I tried to modify the template by including the following packages:

\usepackage[utf8]{inputenc}
\usepackage{ucs}

But I am still getting an error:

> Undefined control sequence. Thích Nhấ

I am hoping there is a simple fix. I welcome any tips, answers, suggestions!

Thanks for the suggestion of adding: \usepackage[T1]{fontenc}

These were the resulting errors by adding that package:

Unicode character ạ (U+1EA1) not set up for use with LaTeX. Thích Nhất Hạ

Unicode character ấ (U+1EA5) not set up for use with LaTeX. Thích Nhấ

I tried the font substitution approach below. These were the resulting errors:

pdfTeX error (font): invalid font identifier. \begin{document}

Font \T5/mdugm/m/n/10=nullfont not loadable: Metric (TFM) file not found. \begin{document}

Font T5/EBGaramond-OsF/m/n/10=ugmr8v at 10.0pt not loadable: Metric (TFM) file not found. \begin{document}

HERE IS MY MWE:

\begin{document}

This is English text, the Vietnamese name
\textvietnamese{Thích Nhất Hạnh} prints as well.

\end{document}

Answer 1

We often use

\usepackage[utf8]{vietnam}

for typing Vietnamese language in LaTeX (I am a Vietnamese).

Hope this helps!

Answer 2

\usepackage{ucs} is never the answer. What you want is to use T5 (Vietnamese) encoding for the name. The EB-Garamond fonts don't support Vietnamese, but there is an implementation of Garamond that does, namely mathdesign’s, and the result seems not bad.

In the example code below I only kept the necessary bits.

\documentclass{tufte-book}

\usepackage[T5,T1]{fontenc}
\usepackage[english]{babel}
\usepackage{ebgaramond}

% there is no support of EB-Garamond to Vietnamese
% but `vntex` provides a Garamond font based on mathdesign
\DeclareFontFamilySubstitution{T5}{\familydefault}{mdugm}

% define commands to switch to the Vietnamese encoding
\newcommand{\vietnamese}{\fontencoding{T5}\selectfont}
\DeclareTextFontCommand{\textvietnamese}{\vietnamese}

\begin{document}

This is English text, the Vietnamese name
\textvietnamese{Thích Nhất Hạnh} prints as well.

\end{document}

If you're wanting to switch to XeLaTeX, it's even simpler and the accents come out better.

\documentclass{tufte-book}

\usepackage[english]{babel}
\usepackage{ebgaramond}

\begin{document}

This is English text, the Vietnamese name
Thích Nhất Hạnh prints as well.

\end{document}

Answer 3

I would strongly recommend that you (a) switch to XeLaTeX or LuaLaTeX -- if you want to keep using the microtype package, you should probably go for LuaLaTeX -- and (b) employ text fonts that have the Vietnamese glyphs all set up. There are many such OpenType fonts by now. I've had good experience with Noto Serif and Noto Sans; both of these fonts may be downloaded for free from Google. Calibri might be a suitable choice for sans-serif text.

\documentclass{tufte-book}
\usepackage[vietnamese,english]{babel}
\usepackage{fontspec}
\setmainfont{Noto Serif}
\setsansfont{Noto Sans}
\newcommand{\blurb}{The Vietnamese name Thích Nhất Hạnh prints as well.}
\begin{document}
\blurb

\sffamily
\blurb

\setsansfont{Calibri}[Scale=MatchLowercase]
\sffamily
\blurb
\end{document}

Answer 4

Well, after a ton of trial and error and cutting and pasting pieces of code from two different threads (this thread and this one: How can I temporarily type a text with different font that defined in the style file?), I have luckily stumbled upon this solution. Even though it doesn't look all that great, it works. It results in a warning that ebgaramond was not found and a substitution made, but no errors! Thank you for all the help and suggestions!

\documentclass{tufte-book}
\usepackage[T5,T1]{fontenc}
\usepackage[english]{babel}
\usepackage{ebgaramond}
\newenvironment{myfont}[2][]{\csname#2\endcsname[#1]}{}% ENVIRONMENT FOR NEW FONT
\newcommand\fontsub[3][]{\begin{myfont}[#1]{#2}#3\end{myfont}}
\newcommand{\Gmd}[1][]{\fontfamily{ebgaramond}#1\selectfont}
\DeclareFontFamilySubstitution{T5}{\familydefault}{ebgaramond}

% define commands to switch to the Vietnamese encoding:
\newcommand{\vietnamese}{\fontencoding{T5}\selectfont}
\DeclareTextFontCommand{\textvietnamese}{\vietnamese}

\begin{document}
Original font \fontsub[\fontsize{10}{16}]{Gmd}{\textvietnamese{Thích Nhất Hạnh}} returned to original font.
\end{document}
