I have been trying to load a Unicode text containing symbols and non-Latin characters. I used the text editor Bluefish. Instead of the proper characters I get boxes containing small numbers. I also installed Bluefish-locale, but there is no difference.
The strange thing is that the same text, loaded in Bluefish under Windows, is correctly displayed. And it uses the same font, so it is not a font problem.
I am guessing that for the proper rendering of non-Latin scripts, some other extension has to be installed, but which?
Can anyone suggest a solution?
