Took them long enough
Back, a long time ago I sat next to the guy doing the VT-220 Arabic Support. That was oh, more than 30 years ago.
Other Editors have had it for years but MS being MS and if they don't want to do it... there is very little one can do to make then.
OTOH, MS could have used the excuse for not doing Arabic support. If they do it, then they might be inadvertantly helping IS plan attacks on the USA.
