Greek letter in title of R Markdown document

Question

Is it possible to include a Greek letter in the title of R markdown document?

I tried this:

---
title: "α-Amylase"
author: "author"
date: "8 March 2017"
output: 
  pdf_document:
  keep_tex: true
toc: yes
toc_depth: 6
---

And this:

---
title: "$\alpha$-Amylase"
author: "author"
date: "8 March 2017"
output: 
  pdf_document:
  keep_tex: true
toc: yes
toc_depth: 6
---

Answer 1

This should work, with html it gives the following output:

---
title: \(\alpha\)-Amylase
author: "author"
date: "8 March 2017"
output: html_document
toc: yes
toc_depth: 6
