#113 Support for codepage 861 (Icelandic)
Hi. Dosbox supports an Icelandic keyboard layout (via "keyb is") but does not support the codepage that was traditionally used on DOS machines in Iceland. This is codepage 861 (https://en.wikipedia.org/wiki/Code_page_861). I ran into this issue when playing with the Fjölnir runtime (https://en.wikipedia.org/wiki/Fj%C3%B6lnir%28_programming_language%29). All its messages and errors are in CP861, so the Icelandic characters in its output are incorrectly displayed by Dosbox.
The program is available here: http://www.hi.is/~snorri/087133-03/fjolnir.zip (bin\fjolnir.exe).
E.g. the first line of its output should be "Fjölnir Íslensk útgáfa 1.00 Raðnúmer: 00000000" but it's incorrectly displayed as "Fjölnir Ñslensk útgáfa 1.00 Raînúmer: 00000000".
I had a look at src/dos/dos_codepages.h but it seems over my head as all its data is autogenerated.
That codepage isn't built in, but you can use a CPI file.
For example, using EGA9.CPX from FreeDOS (an FTP server search engine should find some mirrors for the file), you would use this command in DOSBox: keyb is 861 ega9.cpx
