Of course I do: a brain fart.

That is clearly the most robust strategy, and I scarcely believe that the
run-time cost will be noticeable. So:
private static final char[] hex = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
'A', 'B', 'C', 'D', 'E', 'F'};
private static char[] hexBuffer = {'\\', 'u', '0', '0', '0', '0'};
public String hexRep(char c)
{
hexBuffer[2] = hex[(c >> 12) & 0xF];
hexBuffer[3] = hex[(c >> 8) & 0xF];
hexBuffer[4] = hex[(c >> 4) & 0xF];
hexBuffer[5] = hex[c & 0xF];
return new String(hexBuffer);
}
