In batch mode, (error ...) is handled by external-debugging-output, and the
latter just does:
putc (XINT (character) & 0xFF, stderr);
^^^^^^
To allow multibyte sequences here, we should use something like:

CHECK_NUMBER (character);
- putc (XINT (character) & 0xFF, stderr);
+ ch = XINT (character);
+ len = CHAR_STRING (ch, str);
+ fwrite (str, len, 1, stderr);
#ifdef WINDOWSNT
/* Send the output to a debugger (nothing happens if there isn't one). */
