Error in Publishing. "Error in yaml::yaml.load(string, ...) : Reader error: control characters are not allowed: #98 at 71"

I have the same situation as written in https://github.com/rstudio/rsconnect/issues/115.

Windows 10, RStudio version 1.1.270 (daily build).
Trying to publish to rstudio-connect-1.5.0-7-x86_64 (CentOS 7.x) and got error.

.Rmd document saved in UTF-8.
YAML preamble is:

---
title: "Анализ статистики"
author: "Автор"
date: '`r Sys.Date()`'
fontsize: 12pt
output:
  html_document: default
  pdf_document:
    dev: cairo_pdf
    keep_tex: yes
    latex_engine: xelatex
    includes:
        in_header: mystyles.sty
---

When I change author: "Автор" to non-cyrillic name, e.g author: "author" everything OK.

Start by reproducing the publishing failure using the reported UTF-8 R Markdown YAML preamble, Cyrillic author, Windows locale, and listed R package versions. The report names no repository files or tests; done would be publishing the document successfully without the YAML reader control-character error.
