utf8test

A console (terminal) application to print all unicode characters in UTF-8 encoding. It is useful to test the completeness of fonts and generally to look up some unicode characters.

Syntax

utf8test [ options ]

Options:
	-s code first character to output (hex, accepts prefix "U+")
	-e code last character to output (hex, accepts prefix "U+")
	-f fmt  format (default "uch"; max length: 16)
		h       show hex byte sequence
		c       show UTF-8 character
		u       show unicode notation ("U+xxxx")
	-d char delimiter within one character (default '\t')

The default mode of operation and will print all unicode characters using one character per line and show

• the U+XXXX notation in first column
• the raw UTF-8 character in second column (this is the character itself, which is shown if the current font supports it)
• following are the bytes in hexadecimal

Sample output (shortened)

U+0000  ^@      00
U+0001  ^A      01
U+0002  ^B      02
U+0003  ^C      03

Remarks

• Please make sure that your console/terminal is set to UTF-8, otherwise the output probably won't make any sense for you.
  • You will be warned about such condition (but it is probably not reliable).
• It is advisable to pipe the output to a pager to slow down the output.
