htlatex、garamond 字体以及空的“ff”和“fi”字符串

Question

我偶然发现了一个问题的延续，似乎已经解决了tex.stackexchange.com/questions/162626/，但如果我使用某种形式的 Garamond 字体，问题又会出现。建议的解决方案均无效。

我在 Debian Linux 10“Buster”上使用 TeX Live 2018。

首先，这是 test.tex

\documentclass{article}
%\usepackage{garamondx}
%\usepackage{ebgaramond}
%\usepackage{urw-garamond}
%\usepackage[urw-garamond]{mathdesign}
%\usepackage{cmbright}
\usepackage{helvet}

\begin{document}

\section{Letters}
\subsection{Valid Letters}
AA Aa aA aa\\
BB Bb bB bb\\
CD Cd cD cd\\
\subsection{Invalid Letters}
FF Ff fF ff\\
FI Fi fI fi\\

\section{Strings}
a string of text\\
a fine string of text\\
a definition of an efficient and fine string of text\\
finally, the problem is solved!\\

\end{document}

现在配置文件：

\Preamble{xhtml,NoFonts, -css}
\Configure{HtmlPar}
{\EndP\Tg<p>}
{\EndP\Tg<p>}
{\HCode{</p>\Hnewline}}
{\HCode{</p>\Hnewline}}
\Configure{emph}{\ifvmode\ShowPar\fi\HCode{<em>}}{\HCode{</em>}}
\Configure{textbf}{\ifvmode\ShowPar\fi\HCode{<b>}}{\HCode{</b>}}
\Configure{textit}{\ifvmode\ShowPar\fi\HCode{<i>}}{\HCode{</i>}}
\Configure{textsc}{\ifvmode\ShowPar\fi\HCode{<font style="font-variant: small-caps">}}{\HCode{</font>}}
\begin{document}
\EndPreamble

并调用：

make4ht -u -c test -s test

Answer 1

问题是没有支持 EB Garamond 或您测试的其他字体的字体文件。tex4ht需要支持htf 文件适用于 8 位字体。它们包含从字体字符到 Unicode 的映射，这对于连字或重音字母等内容尤其必要。

创建htf文件并不容易，大多数htf文件都是手工创建的。当找不到htf字体时，将使用默认映射。它通常适用于基本的拉丁文本，但对于符号，尤其是连字符，它可能不起作用。

当您运行命令时，您会看到有关 EB Garamondtex4ht缺少文件的提示：htftex4ht test

(/usr/local/texlive/2018/texmf-dist/fonts/tfm/public/ebgaramond/EBGaramond12-Italic-osf-sc-ot1.tfm)
--- warning --- Couldn't find font `EBGaramond12-Italic-osf-sc-ot1.htf' (char codes: 0--127)
(/usr/local/texlive/2018/texmf-dist/fonts/tfm/public/ebgaramond/EBGaramond12-Italic-osf-ot1.tfm)

--- warning --- Couldn't find font `EBGaramond12-Regular-osf-ot1.htf' (char codes: 0--138)

我创建了一套工具，叫做赫特根用于自动htf文件生成。以下 Lua 脚本使用提供的库Htfgen来生成运行htf中报告为缺失的字体的文件tex4ht。将其保存为makehtf.lua：

kpse.set_program_name("luatex")
local lfs = require "lfs"
local htflib = require "htflibs.htflib"
local fontobj = require "htflibs.fontobj"

-- load a map file. pdftex.map should contain all possible fonts
local fonts = fontobj("pdftex")


local function write_file(htfname, contents)
  local f = io.open(htfname, "w")
  f:write(contents)
  f:close()
end

local function find_missing_fonts(tex4ht_output)
  local missing_fonts = {}
  for htf_font in tex4ht_output:gmatch("Couldn't find font `(.-)%.htf") do
    table.insert(missing_fonts, htf_font)
  end
  return missing_fonts
end

-- make test run on the dvi/xdv file to find unsupported fonts
local function run_tex4ht(dvifile)
  -- redirect stderr
  local ext = dvifile:match("^.+(%..+)$")
  local command = io.popen("tex4ht -" .. ext .. " " .. dvifile .. " 2>&1", "r")
  local result = command:read("*all")
  command:close()
  return find_missing_fonts(result)
end

local missing_fonts = run_tex4ht(arg[1])

for _, fontfile in ipairs(missing_fonts) do
  local fontobject 
  -- the virtual fonts have priority over tfm fonts
  local vffile = kpse.find_file(fontfile, "vf")
  if vffile then
    fontobject = fonts:load_virtual_font(vffile)
  else
    local tfmfile = kpse.find_file(fontfile, "tfm")
    if tfmfile then
      fontobject = fonts:load_tfm_font(tfmfile)
    end
  end
  if fontobject then
    local htfname = fontfile .. ".htf"
    print("writing " .. htfname)
    write_file(htfname, htflib.fontobj_to_htf_table(fontobject).."\n" .. htflib.fontobj_get_css(fontobject) .."\n")
    for _, missing in ipairs(fontobject.missing_glyphs) do
      print("Missing glyph", missing)
    end
  end

end

可以这样执行：

texlua makehtf.lua test.dvi

它应该打印如下内容：

writing EBGaramond12-Regular-osf-sc-ot1.htf
writing EBGaramond12-Italic-osf-sc-ot1.htf
writing EBGaramond12-Italic-osf-ot1.htf
writing EBGaramond12-Regular-osf-ot1.htf

并创建这些htf文件。我会将它们发布在这里。
