在TCPDF和FPDI中使用中文字體。 編碼問題

Question

我正在編寫一個生成漢字工作表的腳本（以便學生可以生成和練習寫作）

該腳本從index.php中的表單傳遞了15個字符串。 然后將字符串分解為15個元素的數組（每個元素為一個漢字）。 當我想使用Write（）函數用這些字符填充文件時，就會出現問題，我已經使用輸入來選擇合適的圖像而沒有任何問題，但是現在正是字體的編碼使我很難受。

PS。 我需要使用草書/手寫字體，因為默認的“打印”字體不適合手寫練習。 理想情況下，我想使用HDZB_36.TTF或Sharp常規腳本字體

請參閱下面的代碼以及使用某些不同字體得到的錯誤圖像。

Answer 1

只是一個建議：

• 您生成的worksheet.pdf文件應該與字母具有相同的編碼。
• PDF應該具有適當的編碼，請參閱： https : //stackoverflow.com/a/10656899/1933185
