我在准备用于TCPDF的PHP使用的自定义OTF字体和AFM文件（Postscript类型1资源）时遇到了问题。
PHP编程的插槽没有打印fontfontge有验证错误，所以我认为我的任务是用fontforge修复字体，但我不知道如何诚实。
使用fontforge打开源字体会出现以下验证错误：
The glyph named mu is mapped to U+00B5
But It's name indicates it should be mapped to U+03BC
The glyph named Delta is mapped to U+2206
But It's name indicates it should be mapped to U+0394
The glyph named fi is mapped to U+F001
But It's name indicates it should be mapped to U+FB01
The glyph named fl is mapped to U+F002
But It's name indicates it should be mapped to U+FB02
你们能帮我一把吗，让这些字符在我的PHP脚本中"可见"吗？
感谢
我在跟踪错误时有点被误导了。验证错误仍然会发生，但我不得不用调整我的TCPDF对象
$pdf->setFontSubsetting(false);
以防止压缩字体。
