From 93292980f390b9245d8e3ce9b0b6c94ee45be217 Mon Sep 17 00:00:00 2001 From: Akira Yokosawa Date: Thu, 5 Sep 2024 14:09:41 +0900 Subject: [PATCH] docs: kerneldoc-preamble.sty: Suppress extra spaces in CJK literal blocks In zh_CN part of translations.pdf, there are several ASCII-art diagrams whose vertical lines look sometimes jagged. This is due to the interference between default settings of xeCJK and fancyvrb (employed in sphinxVerbatim env), where extra space is inserted between a latin char and a non-latin char when they are next to each other (i.e., no explicit white space). This issue can be suppressed by invoking \CJKsetecglue{} at the beginning of every sphinxVerbatim enviornment. \AtBeginEnvironment, provided by the etoolbox package, is useful in this case.
