One hour later, it appears that sshguard is working fine. It's structured as a dozen binaries or so, but it has no dependencies. I haven't done any CPU usage measurements, but I haven't seen it appear in top's output.

That was a long time ago. Traditionally, character's under Unix were encoded in a locale-specific manner: ISO 8859-1 in Western Europe, ISO 8859-2 in Eastern Europe, EUC-JP in Japan, etc. In the 1990s, there was a major push to get XF
