The <hex_digits> (in blue if you're using a color terminal is the hexadecimal value of a byte that is not part of a valid character in your current locale.

You can translate the hex value(s) to octal using printf. And then you can use tr to delete those characters. For example, if vi shows you <82>, <84>, and <fe>; you could use:

Code:

printf '\\%03o\n' 0x82 0x84 0xfe

which would give you:

Code:

\202
\204
\376

and then you could use:

Code:

LC_ALL=C tr -d '\202\204\376' < input_file > output_file

to remove all occurrences of those three byte values from input_file with the updated contents stored in the file output_file.

pango::attrlist

Pango::AttrList(3pm)					User Contributed Perl Documentation				      Pango::AttrList(3pm)

NAME

       Pango::AttrList - holds attributes that apply to a section of text

DESCRIPTION

       Pango::AttrList is a collection of Pango::Attributes.  These attributes annotate text with styles.

HIERARCHY

	 Glib::Boxed
	 +----Pango::AttrList

METHODS

   attrlist = Pango::AttrList->new
   $list->change ($attr)
       o   $attr (Pango::Attribute)

   attrlist or undef = $list->filter ($func, $data=undef)
       o   $func (scalar)

       o   $data (scalar)

       Since: pango 1.2

   $list->insert ($attr)
       o   $attr (Pango::Attribute)

   $list->insert_before ($attr)
       o   $attr (Pango::Attribute)

   attriterator = $list->get_iterator
   ($attr_list, $text, $accel_char) = Pango->parse_markup ($markup_text, $accel_marker)
       o   $markup_text (string)

       o   $accel_marker (character)

       Parses marked-up text to create a plaintext string and an attribute list.

       If $accel_marker is supplied and nonzero, the given character will mark the character following it as an accelerator.  For example, the
       accel marker might be an ampersand or underscore.  All characters marked as an acclerator will receive a PANGO_UNDERLINE_LOW attribute, and
       the first character so marked will be returned in $accel_char.  Two $accel_marker characters following each other reduce to a single
       literal $accel_marker character.

       May croak with a Glib::Error in $@ on failure.

   $list->splice ($other, $pos, $len)
       o   $other (Pango::AttrList)

       o   $pos (integer)

       o   $len (integer)
