My xCHM Reader can't open any file. When I try to open a chm file I get this error:
../src/common/unichar.cpp(65): assert "Assert failure" failed in ToHi8bit(): character cannot be converted to single byte 2 1 Answer
The program "Archmage" can solve this problem. Just install it from repository and type in command line:
$ archmage 'name_of_your_chm_file'*chm-file is an html archive, you will see a result of this operaion in the folder with your chm-file name + '_html' extension.
