What I don't like about PRI #399 is its proposing to use
default-ignorable characters. On a non-vexillology-aware platform, I'd
like to see something informative, albeit not resembling a flag, but
indicative of the intention to display a flag, like RIS can be, as
opposed to nondescript white flags.
