a little bit japanese in romaji

I do not have japanese characters on computer right now(I am trying to solve this problem), but I want to write something in it. So this is romaji.

Hajimemashite, watashi wa Saltanat desu. Dodzo yoroshiku onegaishimasu. Kazafusutan no keika Astana ni<strike>de</strike> sunde imasu. Astana wa samui machi desu. Demo natsu wa atsui desu.
Watashi wa gakusei desu. Keizai o benkyoshitemasu. Sore kara eigo to nihongo o benkyoshitemasu. Watashi wa iroiro gengo o bekyosuru no(=koto)ga suki desu.
