sed replacing specific characters and control characters by escaping
Code:
sed -e "s/[\.\/\%'=:\(\)\`_\"\@\;\+\*\#\$\?\!]/ /g" old.txt > new.txt

While I do know some control characters need to be escaped, can normal characters also be escaped and still work the same way? Basically I do not know all control characters that have a special meaning, for example, ?, ., % have a meaning and have to be escaped to be replaced.

Does the above sed work as expected to replace all of the below characters with a space?
Code:
 ,
  .
  @
  /
  #
  :
  (
  )
  '
  *
  %
  $
  +
  ?
  _
  =
  "
  !
  ;

mdbfontsize

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME

       mdbFontSize - Font Size

DESCRIPTION

       In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
       bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
       about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.

       FONT-SIZE-ADJUSTMENT ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ADJUST-RATIO ::= INTEGER

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:

	   ((devanagari-cdac) 150)

       instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
       'devanagari-cdac'.
