我正在尝试 Context（MkIV、luatex），在下面的代码片段中，双引号是直的，而单引号则变成了“前向”引号。
仅当我选择新的等宽字体（例如 Consolas）时才会发生这种情况。（我得到的引号不是 Consolas 直引号。）
我怎样才能关闭它？
\setuppapersize[A4][A4]
% Without the switch to consolas, the quotes are fine.
\definefontfamily[f][serif][Garamond]
\definefontfamily[f][sans][Gill Sans MT][rscale=0.9]
\definefontfamily[f][mono][Consolas][rscale=0.8]
% tried: tlig-no,trep=no but didn't help
\setupbodyfont[f]
\setupbodyfont[12pt]
\starttext
\starttyping
-- in lua you can use both single and double quotes
a = 'single quoted'
b = "double quoted"
\stoptyping
\stoptext
答案1
您必须设置features=none。（我使用 Latin Modern Mono，因为我没有 Consolas）
\definefontfamily[f][mono][Latin Modern Mono][rscale=0.8,features=none]
\setupbodyfont[f]
\starttext
\starttyping
-- in lua you can use both single and double quotes
a = 'single quoted'
b = "double quoted"
\stoptyping
\stoptext
