Wikipedia indicates that there are multiple flavors of UTF-8, but here is one solution.
Wikipedia lists Unicode characters: https://en.wikipedia.org/wiki/List_of_Unicode_characters Way towards the bottom of the article is a table of math symbols.

Subject: [R] UTF-8 to the console

[External Email]

Dear all,

I want to send UTF-8 characters to the console. Font in the GUI-Preference 'Lucida Console', supporting the desired symbols:
greater than or equal: UTF-8 2265, HTML-entity ≥ HTML-Unicode ≥ TeX \ge approximately equal: UTF-8 2248, HTML-entity ≈ HTML-Unicode ≈ TeX \approx

txt <- "x ≥ y, x \u2265 y; a ≈ b, a \u2248 b"
Encoding(txt) <- "UTF-8"
[1] "x = y, x = y; a \230 b, a \230 b"
cat(txt, "\n")
x = y, x = y; a ˜ b, a ˜ b

Desired "x ≥ y, x ≥ y; a ≈ b, a ≈ b"

I'm sending the email in UTF-8. Don’t know how @r-project.org is configured (ASCII?) If you see garbage, I'm sorry but you should get the idea.

R 4.2.0 on Windows 7 (UCRT10.0.10240.16390) and Windows 11.
