Text editor/viewer with ANSI codes rendering support for Windows [closed]
The open-source editor Atom has the package language-ansi-styles. It supports all kinds of formatting except ;r;g;b.
I've been looking for a solution to display the ANSI colors as well (for program debug output readability) and stumbled upon Sublime Text (paid software with trial http://www.sublimetext.com/) with a the ANSIescape package (https://github.com/aziz/SublimeANSI or installed through the package control).
It supports coloring and the bold escape is recognized but not displayed, although a special color can be assigned to it in the settings file. Also worth noting that this plugin shows text in read-only mode, and needs to be turned off if editing is necessary.
Here is the screenshot provided on the github, and I have personally tried it and verified it works:
You might have some more luck with ASCII/ANSI utilities, like the ones listed here:List of ASCII/ANSI/NFO utilities
