How to get UTF-8 to work with mIRC
To get UTF-8 working properly with mIRC, you need at least version 6.17 of mIRC, which you can get here: http://www.mirc.com/get.html. Non-windows users are assumed to have been using clients with proper encoding support for years already.
However, mIRC will not display and encode text in UTF-8 by default, you need to change a couple of settings first. There are two places you need to change the settings in: the "mIRC Options" dialog and the "Select Font" dialog.
To reach the options dialog, you can press "Alt+O" in any window in mIRC, or you can go to it via either the "View ⇒ Options...", or the "Tools ⇒ Options..." menus.
Once you have reached the options dialog, you need to go to the IRC ⇒ Messages section via the category list on the left-hand side of the options dialog.
What needs to be changed
In there, you need to make sure that these to options are checked:
- UTF-8 display
- Multibyte editbox
And you should make sure that the following options are unchecked:
- SJIS/JIS conversion - because this is not 7-bit ASCII compatible, and will thus break UTF-8 and every other encoding that might be used.
- Multibyte display - because this will break bold/underline/reverse/colour codes when used with text encoded in UTF-8.
The fonts dialog works in a fairly odd way. You can set a specific font for each window you have open, and you can also set a default font to use for every window that does not have a specific font set. You also need to set the default font differently for channels and private messages, as well as status windows and other windows. In order to get to the fonts dialog for an active window, you can use the "View ⇒ Font..." menu, or the "System menu ⇒ Font..." (to reach the system menu, you can click on the window-icon that you normally double-click in order to close a window. Or you can use the "Alt+-" hotkey).
What needs to be changed
Once you've reached the font dialog, you need to change the following things:
- The "UTF-8:" section to "Display and encode".
- If you want to set this as the default setting for windows whose options you have not set (recommended), check the "Set as default channel font" setting. (Assuming you're changing the option for a channel window. If you're changing it for a private message window, the setting is called "Set as default chat font".)
It is also recommended that you use a font that can actually display unicode characters.
Q: I have changed all of these settings but I still get strange symbols or empty boxes when someone sends UTF-8 encoded text to me!
- A: This means you don't use a font that has the characters being used. Note, recent windows versions come with 'Lucidia Sans Unicode' - which has most glyphs you're likely to want. Otherwise, you can try use these:
Q: How can I fix other problems like characters not in system codepage being sent as ? marks, or logs/dcc file names being scrambled?
- A: Upgrade to 6.2 which fixes various encoding bugs - and make sure that 'multibyte display' is off.
