To get pIqaD to work in Pidgin on Windows you have to do the following (after installing the Windows pIqaD package):
Create a file called pango.aliases in c:\program files\pidgin\GTK\etc\pango (32-bit Windows) or c:\program files(x86)\pidgin\GTK\etc\pango\ (64-bit Windows)
Put this in that file:
“sans” = “sans,meiryo,malgun gothic,microsoft jhenghei,microsoft yahei,gisha,leelawadee,pIqaD”
Save the file and restart pidgin. You should now be able to see and write in pIqaD over any protocol that supports UTF-8.
If “sans” is not your current theme font, you can either change “sans” in the above line to whatever font you use (make sure you change it in both places), or you can change your font in Pidgin to “Sans Normal” (it’s under Tools/Preferences/Conversations/Font, uncheck “Use font from theme” and select “Sans Normal” from the “Conversation font” popup window).
Note: The list of fonts above should enable pidgin to show all unicode characters. If you get any unicode characters that aren’t showing properly (if they show little boxes with 4 letters and/or numbers in them) then another font needs to be added to the list. Comment on this blog post with the characters and the language they are from and I’ll try and find the font that needs to be added to the list.
