How to remove escape sequences from a text file?

Hello friends,

Could anyone please advise on how to remove escape sequences from a text file?

Code:
$ file input.txt
input.txt:       ASCII English text, with escape sequences

I'm able to see those escape characters when opened in vi editor like shown below:

Code:
^[^[&l0O^[(s16.66h^[&a10L^[&l64F^[&l1S^[&a1G
TEST^[&a           73CPrint Date 25/09/15^[&a          105CPage      1
TRAVEL

but not when I run more command. That's how I want the file to be (by removing the escape seq - we also need to remove entire line if it has only escape sequences)

Code:
TEST 			Print Date 25/09/15 	                 Page 1
TRAVEL

Please advise,

many thanks in advance!!

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
