 Hi @mattpr, welcome WordPress Trac! Thanks for the report.

 It is, see #12775 (also #20890 and #28187).

 That said, I think being able to edit the file in Windows Notepad is
 actually a disservice to most Windows users, as it inserts the
 [https://en.wikipedia.org/wiki/Byte_order_mark UTF-8 byte order mark],
 causing the
 [https://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F
 Headers already sent]  PHP warning (as seen in #27373, #27974, #28490,
 #32575, #33626, #36213, #37036, and some other tickets).

 The issue mostly happens in non-Latin locales, where `wp-config-
 sample.php` is translated and includes non-ASCII characters. The solution
 is then to re-save the file in UTF-8 without BOM using Notepad++ or other
 editor.

 `Warning: Cannot modify header information - headers already sent by
 (output started at .../public_html/wp-config.php:1)` has been the
 [https://codex.wordpress.org/%D0%A7%D0%90%D0%92%D0%9E/Cannot_modify_header_information
 top FAQ entry] on https://ru.wordpress.org/support/ for almost 10 years
 now. The page specifically advises against using Notepad for editing `wp-
 config.php`.

 So, while the original intention was to make it easier to edit the file in
 Notepad, maybe we could reconsider that?

 On the other hand, more and more people these days get WordPress from
 their hosting provider without manually editing files, so perhaps making
 the change now is not worth it.
