/**
 * @bug 4139940
 * Couldn't reproduce this bug -- probably was fixed earlier.
 *
 * ORIGINAL BUG REPORT:
 * -- basically, hungarian for monday shouldn't have an \u00f4
 * (o circumflex)in it instead it should be an o with 2 inclined
 * (right) lines over it..
 *
 * You may wonder -- why do all this -- why not just add a line to
 * LocaleData?  Well, I could see by inspection that the locale file had the
 * right character in it, so I wanted to check the rest of the pipeline -- a
 * very remote possibility, but I wanted to be sure.  The other possibility
 * is that something is wrong with the font mapping subsystem, but we can't
 * test that here.
