How about these characters?

There exist no "f" sound in Korean.

For imported words, "f" is represented by "p"

For example, "waffle" becomes "wapple."

I think this sounds cute.

However, sometimes it is inconvenient.

Korean characters consist of a consonant part(s) and a vowel part.

For example, like this.

카 [ka], 키 [ki], 쿠 [ku], 캐 [ke], 코 [ko]

If you reverse left and right of the consonant "ㅋ",

It look like "F", isn't it?

Then [fa, fi, fu, fe, fo] sounds can be written like this.

In Japanese, a character ヴ [v] is used only for imported words.

In Italian, letters j, k, w, x, y are used only for imported words.

May be it is high time to introduce a new character representing "f" in Korean.
