function get_filename_charsets(charsets: String): Boolean {
    // Gjs wrapper for g_get_filename_charsets()

Determines the preferred character sets used for filenames. The first character set from the charsets is the filename encoding, the subsequent character sets are used when trying to generate a displayable representation of a filename, see GLib.filename_display_name.

On Unix, the character sets are determined by consulting the environment variables `G_FILENAME_ENCODING` and `G_BROKEN_FILENAMES`. On Windows, the character set used in the GLib API is always UTF-8 and said environment variables have no effect.

`G_FILENAME_ENCODING` may be set to a comma-separated list of character set names. The special token "@locale" is taken to mean the character set for the [current locale][setlocale]. If `G_FILENAME_ENCODING` is not set, but `G_BROKEN_FILENAMES` is, the character set of the current locale is taken as the filename encoding. If neither environment variable is set, UTF-8 is taken as the filename encoding, but the character set of the current locale is also put in the list of encodings.

The returned charsets belong to GLib and must not be freed.

Note that on Unix, regardless of the locale character set or `G_FILENAME_ENCODING` value, the actual file names present on a system might be in any random encoding or just gibberish.

Since 2.6


return location for the null-terminated list of encoding names


true if the filename encoding is UTF-8.
