I have an existing program (codes) to generate PDF file via TCPDF. 我有一个现有程序（代码），可通过TCPDF生成PDF文件。 It works fine even contain non-English characters in most cases, but now, when the content has either two simplified Chinese characters 喆 (unicode number: 21894) or 旻 (unicode number: 26107), all Chinese characters will be converted to rectangle (invalid character). 在大多数情况下，即使包含非英文字符也可以正常工作，但是现在，当内容具有两个简体中文字符喆 （统一码：21894）或旻 （统一码：26107）时，所有汉字都将转换为矩形（无效字符）。

I tried to check the uni2cid_ag15.php, and I can find the mapping of those two words and the mapped cids are correct. 我尝试检查uni2cid_ag15.php，发现这两个单词的映射和映射的cid是正确的。 Is anyone know the reason for converting the Chinese characters incorrectly with that specific character(s)? 有人知道用该特定字符错误地转换汉字的原因吗？

I found out the solution by using new encoding "GB18030" for php function mb_convert_encoding, instead of "GB2312". 我通过为php函数mb_convert_encoding使用新的编码“ GB18030”而不是“ GB2312”找到了解决方案。 Those characters can be generated in the PDF without problem. 这些字符可以毫无问题地在PDF中生成。
