What is the easiest way to insert Thai words in an English lyx document?

Question

I am a big fan of Lyx, but find that when I want to include a few Thai words within an English document, things start getting difficult.

There are many solutions posted online, not all of which are easy to follow for non-TeX-experts like myself. Some of the solutions appear not to work with Lyx.

What is the easiest way to insert Thai words into an English Lyx document?

Answer 1

After trying several methods, the most efficient way I have found is to do the following:

For all of the following you need to go be in Document Settings, which is in the "Document" menu.

1. In the "LaTeX Preamble", add this:

   \usepackage{fontspec}
   \setmainfont{Norasi}
   \XeTeXlinebreaklocale ’th_TH’
   

2. In the "Fonts" section, tick "Use non-TeX fonts (via XeTeX/LuaTeX)".

3. In the "Output" section, Default Output format box, choose "PDF (XeTeX)".
4. Press "OK".

When you click "view" or "update" document, you will now see a PDF which should show both Thai and English words correctly.

• This makes it easy to switch between Thai and English: no ERT is required in the document.
