How can I read korean in windows?

There is also the possibility of simply stacking a (sequence of) medial(s) (jungseong) – and then a (sequence of) final(s) (jongseong) and/or a Middle Korean pitch mark, if needed – on top of the (sequence of) initial(s) (choseong), if the font has medial and final jamos with zero-width spacing that are inserted to the left of the cursor or caret, thus appearing in the right place below or to the right of the initial. If a syllable has a horizontal medial (ㅗ, ㅛ, ㅜ, ㅠ or ㅡ), the initial will probably appear further left in a complete syllable than is the case in pre-formed syllables due to the space that must be reserved for a vertical medial, giving an aesthetically poor appearance to what may be the only way to display Middle Korean Hangul text without resorting to images, romanisation, replacement of obsolete jamo or non-standard encodings. However, most current fonts do not support this.
