『心配しないで。私、元気だから　(^-^)v』「あ・・・顔文字？」

『。、(^-^)』「・・・？」

'Don't worry. I'm doing fine (^-^)v' — 'Oh... an emoticon?'

Literal

'Worry don't. I, fine is-[because-から] (^-^)v' 'Ah... face-character?'

A short exchange showing the Japanese reaction to seeing a Western-style emoticon. 顔文字 (かおもじ) literally 'face-character' is the general Japanese term for emoticons — includes Japanese-style ones like (^-^) which are oriented upright rather than sideways like Western :). Note the negative imperative 心配しないで ('don't worry'), the soft ending ~で form as polite negative command. ~から here provides explanation ('because I'm fine').
