Hi,
Are you trying to use module "utf8conv"? If you are, it has to be installed as a module before using it.
Steps:
1. download module file "utf8conv.tar.gz" and unzip. the unzipping will create a folder "utf8conv" with all scripts in
2. copy the folder into ATutor "mods" folder. If your ATutor is installed at "/home/www/web16/html/ATutor/", copy "utf8conv" into "/home/www/web16/html/ATutor/mods/"
3. login ATutor as administrator, click "Install Modules", select "utf8conv", click button "Install"
4. Once installed, select module "UTF8 Conversion", click "Enable"
5. now the module is installed and enabled. you will have a new tab "UTF8 Conversion". Go ahead and enjoy!
