lua io.popen() 带有 ö、ä、ü、ß 的命令

我尝试了your_filename:fromutf8()，无论我做什么都不起作用。我还尝试了chcp 1252 & echo weiß，它什么也没改变，但最终我搞定了。

``` local ersetzen = { [142] = string.char(196), --Ä [132] = string.char(228), --ä [153] = string.char(214), --Ö [148] = string.char(246), --ö [154] = string.char(220), --Ü [129] = string.char(252), --ü [225] = string.char(223), --ß }

local function split(...) local output = {} for i = 1, string.len(...) do output[i] = string.sub(..., i, i) end return output end

local function konvertieren(datei) local a = split(datei) local rest = {} for k, v in pairs(a) do table.insert(rest, (ersetzen[string.byte(v)] or v)) end return table.concat(rest) end

它可能有更简洁的方法，但这对我很有效。

使用方式: your_filename:from850()
