將以下代碼從Pascal翻譯爲Lua，其目的是將其作爲阿拉伯語腳本 - 形成阿拉伯語字符串，並將表中存儲的有序字形類型與位圖字體一起使用。 它適用於具有唯一字符的字符串，例如：字符串（「أحمدقطعالجزر」）可以正常工作，但是當重複字符時會出現問題，請考慮將三個字符串（「مهم」）形成爲鏈接字形像這樣（「مهم」）爲（م）s（而不是（مهم））返回第一個字形類型，循環總是爲重複字符提供第一個字形類型。
這裏是循環： 在Lua中循環顯示阿拉伯字符串和等效表格字形？
local current, nxt = ''
local linkBefore , linkAfter = false , false
function linkChars(text)
linkBefore = false
for i = 1 , utf8.len(text) do
current = utf8.sub(text , i , i)
if i < utf8.len(text) then
nxt = utf8.sub(text , i+1 , i+1)
else
nxt = ''
end
linkAfter = (nxt > first and nxt < last) and (glyphTable[nxt].final or
glyphTable[nxt].medial)
if (current >= first and current <= last) and current ~= nxt then
glyph= glyphTable[current]
if (linkBefore and linkAfter) and (glyph.medial) then
text =string.gsub(text,current,glyph.medial)
elseif linkAfter and (glyph.initial) then
text =string.gsub(text , current , glyph.initial)
elseif linkBefore and(glyph.final) then
text =string.gsub(text , current , glyph.final)
elseif glyph.isolated then
text =string.gsub(text , current , glyph.isolated)
end
linkBefore = (glyph.initial or glyph.medial) and linkAfter
else
linkBefore = false
end
end
text=text:gsub("([\194-\244][\128-\191]*)" , string.reverse):reverse()
return text
end
可能，我做錯了什麼是
的（對）的循環遍歷所有的字符爲每個條件時，我必須通過每個循環的條件炭？然而 ，如何使其正常工作？

你的代碼太凌亂，請正確格式化代碼。 –
完成了，希望現在很清楚 –
@hasanbaabad 我修好了你的想法。我希望你在你的編輯器上比在這裏做得更好:) – Piglet
