Can you tell in more detail how did you do step 6?  I tried a simple
replacement with M-%, but didn't see the result you reported, so I
assume that's not what should be done.

Thanks.

[Message part 1 (text/plain, inline)]

If you take the first "table" of char sequences and IPA glyphs in
the *Help* buffer from C-h I i p a RET and run it through a pipeline,
"perl  -p -e 's/ +/_/g;s/\|/\\vert{}/g;s/_/  \| /g;s/^/\| /;s/$/ \ |/'" ,
you'll
have the right data.

Then if you put that into an org-mode buffer and cause the "special
symbols" like \vert to be displayed, type C-c C-x \.

Now if you position to the 1st cell in the table and start typing TAB as
the cursor moves through the table, I believe you will see strange results.

I'm including a file with the output of the pipeline

Thanks,
Bruce

I can reproduce the "strange results", i.e. bad column alignment in the
table, in current master with -Q but not with my initializations.  The
crucial difference is the font used: with -Q it is this:

"-unknown-Liberation Mono-normal-normal-normal-*-15-*-*-*-m-0-iso10646-1"

and with my initializations it's this:

"-unknown-DejaVu Sans Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1"

If I start with -Q, do `M-x set-frame-font' and enter the latter font,
and then carry out the above recipe, the table columns are all correctly
aligned.

I noticed that the alignment was already not completely correct before
executing `C-c C-x \': some characters have a narrower width, e.g. the
character #x2c8 (MODIFIER LETTER VERTICAL LINE) in the second column of
the second row.  With my initializations this character is displayed in
the same font as the default font listed above, but with -Q it is
displayed in a different font from the default font:

"-unknown-DejaVu Serif-normal-italic-normal-*-15-*-*-*-m-0-iso10646-1"

Thanks for investigating this.

Yes, Emacs will try to use the default font for punctuation and symbol
characters, unless the default font fails to support them; then Emacs
will look for a font that does.  If that font is a variable-pitch
font, you will get mis-alignment, if the mode which produces the table
uses whitespace for alignment, and not pixel-granular display
properties.

This is normal, and not a bug.

The solution is to fix your font configuration (e.g., via fontsets
inside Emacs, or by installing/uninstalling fonts).

From reading this thread, it seems like this is not a bug. I'm therefore
closing this bug report.

If this conclusion is incorrect, please reply to this email (use "Reply
to all" in your email client) and we can reopen the bug report.
