Akuma, depending on what file you are grepping, the tab may just be white space. If this is the case, try using quotes and just one space. Example:
grep "xxx iii" filename.ext
One more idea if that doesn't work. If you know of at least one entry in the file you are looking for, you can count the number of spaces your are trying to grep. It would be even more helpful if you could copy and paste what you are trying to find.
Example:
grep "xxx iii" filename.ext
I put five spaces in between in case there where originally five spaces in your tab.
Hope that helps!

I try to remove empty lines from file and use next:
> cat fl.dat|grep -v '^*$'
or
cat fl.dat|sed '/^*$/d'
'grep' does not removes lines with tabs, 'sed' - lines with <tab> and with <spc>
Why it could be?
Is there any option/env-var should I check?
Thank you

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
