All WM text corrupted if built without i18n / nls

[RobPearce]

I have several Gentoo Linux systems and VMs running icewm. A while back, on upgrading to v2.9.7, one of them developed a problem whereby all the text rendered by IceWM (the start menu, the window titles, even the clock) was garbage. Closer inspection showed that only every other character was rendered, so the entry at the bottom of the start menu was "Lgu" (Logout) and the window title of an xterm was "ro@itart" (root@virtualruth)
Initially I backed that system down to v2.8.0 but that's no longer in the Gentoo repositories, so I've done some more digging. The problem is still present at v3.3.1 (I couldn't build 3.3.2) but only if built with NLS and I18N disabled (that particular VM has no need of being internationalised).
My suspicion is that, without i18n, the plain ASCII text is passed to some code that expects wide characters.

Was very easy to fix. Please report sooner. Others benefit too.
