In awk, I'd like to check if a field is blank.
And by blank I mean, the field could be "" or " "
In other words, the field could either be empty, or be filled with spaces.
Would the regex look like this?
$5 ~ // { Action }?
What other ways are there?

getunimap
GETUNIMAP(8) Linux GETUNIMAP(8)NAME
getunimap - dump the unicode map for the current console to stdout
SYNOPSIS
getunimap [ -s ] [ -C console ]
DESCRIPTION
The getunimap program is old and obsolete. It is now part of setfont (1).
The getunimap program outputs the unicode map (also called a "Screen Font Map") for the current console to standard output.
The -C option may be used with Linux 2.6.1 and later to get the map for a console different from the current one. Its argument is a path-
name.
The output of getunimap is of the form
0xAA U+1234 # comment
where 0xAA is the font character code and U+1234 is a unicode character, that if displayed, will be displayed using glyph 0xAA in the font.
Many unicode characters may be mapped to the same glyph.
the Hash symbol # is used as a comment delimiter; characters after a hash sign (to the end of the line) are comments.
The -s option will sort and merge elements, sorting on font character. Hence, it will produce output of the form:
0x22 U+1234 U+5678 U+3456
0x23 U+0023
etc., listing the multiple unicode characters that map to a font glyph.
The output of getunimap is of the form accepted by setfont and psfaddtable
