Как заставить любой язык работать с моим кодом ⇐ C++

[Anonymous]

У меня есть программа, состоящая из трех частей: dll, сервера, который обрабатывает существующий файл через эту dll, и клиентской программы, которая принимает входные данные: имя обрабатываемого файла и символ. Обработка заключается в замене всех пробелов в существующем файле на введенный клиентом символ, имя и символ на замену клиент передает через почтовый ящик. После обработки сервер создает выходной файл через DLL с тем же именем, но с другим расширением. Проблема в том, что некоторые необычные символы воспринимаются неправильно, например арабский, греческий, японский и тому подобное. Обычно консоль нормально видит их в клиенте, но "?" на сервере и после этого в созданном файле. Как я могу заставить их работать правильно? Вот код:
сервер:
