\activatespacehandler

\activatespacehandler

[Aditya Mahajan]

Hi,

\activatespacehandler{on} does not work in MkIV. I guess that this is 
because \controlspace does not give the right glyph in MkIV, possibly 
because, in opentype fonts, \char 32 is the same as regular space.

Any idea how to fix this? Is there a unicode character for visible space. 
A discussion on the xetex mailing list suggests 
http://www.tug.org/pipermail/xetex/2006-February/003095.html 0x2423, but 
that looks very different from \tt\char 32.

Aditya

Actually, the relavant code is in enco-ini.mkiv. So the fix is to set

\def\controlspace{\fastcontrolspace}

in char-act.mkiv, or use \fastcontrolspace in spac-hor.mkiv

The Unicode annotation of that character says "graphic for space", so I
guess it is the right character, but fonts might have not-so-suitable
glyph

  That's two different things: U+2423 is the visual representation of a
white space character (hence it can't be white space since it's meant to
give a cue to the reader that there is something here), while Aditya
actually wants white space.  In this case, U+2423 isn't appropriate.
