标题： An error is reported when an oversized file is parsed in GBK encoding mode. 内容： Version: 2.9.10. When the xmlParseMemory interface is used to parse the oversized file (coded as GBK) in the attachment, an error Huge input lookup is reported. When the file is encoded as UTF8, no error is reported. 附件：
