Great, but there are a couple of issues:

Use KS_currency

No, this is not the correct approach.

Most common 8-bit encodings which are extensions of 7-bit ASCII, place the
euro currency symbol at 0xA4.

Historically, (before the introduction of the euro currency symbol), this was
a generic, 'currency symbol', which saw little use in practice.  The codepoint
was subsequently re-used specifically for the euro currency symbol.

The wscons console fonts that are currently included with OpenBSD, (both
spleen and gallant), have the old currency symbol at this codepoint.

This is a font issue.  The correct encoding on the console is 0xA4.
