The entire parsing of the format string is affected by the multi-byte
character encoding. I don't know how GCC would be able tell that a byte
with the same value as '%' in the middle of string would actually be
interpreted as '%' character rather than a part of an extended multibyte
character. This can easily happen with the ISO 2022-JP encoding.
