使 polyglossia 与 zref-savepos 或 pdfsavepos 协同工作

tag-icon • tag-icon xetex polyglossia output zref
使 polyglossia 与 zref-savepos 或 pdfsavepos 协同工作

当我添加polyglossia包以使用我的希伯来语文本时，它会破坏将坐标写入文件的过程。如果我删除包，polyglossia它就可以正常工作。不确定它是否与有关zref。如果你\newline在每行之间添加一个，它就可以正常工作，但我需要文本以段落的形式流动。

梅威瑟：

\documentclass{article}%
\usepackage{zref-savepos}%

\usepackage{polyglossia}%
\setmainlanguage{hebrew}%
\setotherlanguage{english}%

\defaultfontfeatures{Mapping=tex-text}

\def\mywriting#1{%
    \zsaveposy{#1}%
    \typeout{#1:\zposy{#1}}% Write to log file to double check.
    \write\myoutputfile{#1:\zposy{#1}}%
}%

\newcommand\writingpos[2][]{%
    \mywriting{#2}%
}%

\begin{document}%
\begin{hebrew}
\writingpos{40001001} This is my very long sentence which spans a line or so and it's Y-position at the beginning will certainly have to be different from it's Y-position at the end of this line and I'll use it to test the output of the ZREF package.\writingpos{40001001L}
\writingpos{40001002} This is my SECOND very long sentence which spans a line or so and it's Y-position at the beginning will certainly have to be different from it's Y-position at the end of this line and I'll use it to test the output of the ZREF package.\writingpos{40001002L}

日志文件显示以下内容（正确）：

40001001:42747166
40001001L:40518942
40001002:40518942
40001002L:38159646
40001003:38159646
40001003L:36586782

但输出文件给出了这样的信息（这是不正确的）：

40001001:42747166
40001002:40518942
40001001L:40518942
40001003:38159646
40001002L:38159646
40001003L:36586782

注意第一个数字（ID）顺序的不同。它应该遵循诸如 ...001、...001L、...002、...002L、...003、...003L 等顺序。

luatex 和 xetex 处理 RTL 上下文中写入的方式有所不同。

使用 luatex 您可以获得

40001001:43889459
40001001L:41661235
40001002:41661235
40001002L:39301939
40001003:39301939
40001003L:37729075

使用 xetex 您可以获得

40001001:42747166
40001002:40518942
40001001L:40518942
40001003:38159646
40001002L:38159646
40001003L:36586782

注意顺序不同（由于来源略有不同，数字也不同）
