Seems the thing should be done properly, inspite of how much effort they will
require.

Yes, it's a pity - but the only solution to reduce size is to add an
attribute like "charset" to AW's file format. In this case, files in locale
encoding could be saved - so each cyrillic character will take exactly 1
byte when saved. All Unicode characters that can't be represented as
character in current locale will be written as &#x????; This is more
preferable IMO than UTF8 since it allows grep and sed for native text to be
used.
Any chance to extend AW's file format this way? (Say if somebody provided
patch for this)?
