add option to print utf8 hex sequence

[juhp]

$ whichfont '　'
Character: 　
NuosuSIL-Regular.ttf: "Nuosu SIL" "Regular"

It would be useful here to know the utf8 hex sequence for the character

[juhp]

Searching it seems in this case the character is U+3000 (Ideographic Space)

adding -u to print unicode

[sudipshil9862]

feature added

example:1

$ ./run.sh অA input_char: অA

Character: অ Lohit-Bengali.ttf: "Lohit Bengali" "Regular"

Character: A NotoSans[wght].ttf: "Noto Sans" "Regular"

---

example:2

$ ./run.sh -u অA ninja: no work to do. input_char: অA

Character: অ unicode: U+0041 Lohit-Bengali.ttf: "Lohit Bengali" "Regular"

Character: A unicode: U+0041 NotoSans[wght].ttf: "Noto Sans" "Regular"

[juhp]

$ whichfont অA
:
Character: অ
unicode: U+0041
:

clearly incorrect, though it works for single character

[juhp]

Also I think it would be okay to write the character and codepoint on the same line.

understood the problem

[sudipshil9862]

it was a problem of printing wrong unicode.
