I'm unsure if Noto Sans fonts are installed by default on Windows or macOS.
Similarly, "Myanmar Text" is unlikely to be installed on Linux.
Since there's a list of possible fonts, the list could well be
*platform-independent* — just look for a first match.

Suggestion:
private static final List<String> FONT_CANDIDATES =
List.of("Myanmar MN",
"Padauk",
"Myanmar Text",
"Noto Sans Myanmar");

With the changes that I propose, `FONT_NAME = selectFontName()`, this will be
the only condition: if the font name is `null`, no suitable font is found —
skip the test.

I see no reason for removing this blank line.
