一切pdflatex正常...当我激活语言时，georgian格鲁吉亚语文本不会显示...我知道 fontencoding 从 EU1/2 更改为 TU，但不知道为什么 EU1/2 被激活而 TU 没有被激活...

仅在 ldf 文件中从 EU 切换到 TU 没有帮助......

Answer 1

不幸的是，georgian.ldf尚未更新以支持TU。解决方法很简单：

\documentclass{article}

\usepackage[georgian]{babel}

\usepackage{ifxetex}% load different packages with/without XeLaTex

\ifxetex
  \def\georgianencoding{TU}
  \usepackage{fontspec}
  \setmainfont{DejaVu Serif}
\else  % packages below are not needed with utf8 based engines
  \usepackage[utf8]{inputenc}
  \usepackage[T8M]{fontenc}
\fi
