无法将大多数TTF文件导入TCPDF

Question

我已经阅读了有关该主题的所有教程，我简直无法使它正常工作，示例代码和在线工具也是如此……

当我尝试将大多数.ttf文件导入TCPDF字体时，生成的php文件如下所示：

<?php
$type='TrueType';
$name='FontAwesome5Free-Solid';
$desc=array('Ascent'=>875,'Descent'=>-125,'CapHeight'=>875,'Flags'=>96,'FontBBox'=>'[5000 5000 -5000 -5000]','ItalicAngle'=>-50,'StemV'=>70,'MissingWidth'=>1000);
$up=-123;
$ut=49;
$dw=1000;
$cw=array(

200=>1000,201=>1000,202=>1000,203=>1000,204=>1000,205=>1000,206=>1000,207=>1000,208=>1000,209=>1000,
210=>1000,211=>1000,212=>1000,213=>1000,214=>1000,215=>1000,216=>1000,217=>1000,218=>1000,219=>1000,

250=>1000,251=>1000,252=>1000,253=>1000,254=>1000,255=>1000);
$enc='cp1252';
$diff='';
$file='lol.z';
$originalsize=191836;
// --- EOF ---

基本上所有字符都无效。

这是我使用PHP源或使用为TCPDF制作的在线转换器（例如：http://www.xml-convert.com/en/convert-tff-font-to-afm-pfa-fpdf-tcpdf或http://fonts.snm-portal.com/）得到的结果。

我正在尝试将字体真棒的TTF文件（例如fa-solid-900.ttf）添加到我的TCPDF中，但是出现此错误。

我不知道现在该怎么办。

您需要将FontAwesome导入为Unicode字体。 [也要注意：在此示例中，字符0-255的字符宽度为1000，因为该字体中不存在这些字符，而1000是为丢失的字形宽度定义的宽度。]对于其他出现故障的字体，请尝试导入它们也可以使用Unicode字体或使用不同的编码表。

//Ignore the warnings about undefined indexes on first import. 
//There's no H or x glyphs in the font, so the warning is expected.
$fa = TCPDF_FONTS::addTTFfont('fa-solid-900.ttf',  'TrueTypeUnicode', '', 4);
//Note: using empty string for $enc since this is a Unicode font
//Note: using 4 for $flags to signify a symbol font. 32 for text fonts.
$pdf->setFont($fa);
$pdf->writeHTMLCell(100,120,40,10,"");

//An example inlined with normal text:
$pdf->setFont('helvetica');
$pdf->writeHTMLCell(100,120,40,20,"Should be a gamepad: <span style=\"font-family:$fa;\">&#xf11b;</span>");

测试输出结果的附加屏幕截图：

测试脚本：

<?php
//Update to your TCPDF path
include 'TCPDF/tcpdf.php';

$pdf = new TCPDF('P', 'mm','Letter', true, 'UTF-8', false, true);
$pdf->addPage();
$pdf->setFontSubsetting(true);
$fa = TCPDF_FONTS::addTTFfont('fa-solid-900.ttf',  'TrueTypeUnicode', '', 4);

$testtext = "Font name: {$fa}<br>".
  "Should be a gamepad: <span style=\"font-family:$fa;\">&#xf11b;</span>";
$pdf->writeHTMLCell(100,10,10,10,$testtext);
$pdf->Output(dirname(__FILE__).'/fasolid-test.pdf', 'F');
