Hi,

I found another case. The problem is with the backquote, or "acute accent"
Which also looks like this: `

If an html file includes this character, displaying the html fails.
This is even if the equivalent html code ` is used.

The error I get is:
/usr/local/share/TeXmacs/progs/convert/tools/xmltm.scm:150:7: In
procedure string-replace in expression (string-replace s cork-grave
...):
/usr/local/share/TeXmacs/progs/convert/tools/xmltm.scm:150:7: string
contains #\nul character: "\"
\\t\\n\"\\'\x00<gtr><less>=%;,|&\\{()\\}\""

The acute was where above there is a '\x00'. (I know, the text looks
strange - it explains what are the default wordbreaks in the "options"
documentation in R.)

I think that was also the problem in this half-year old email below.

Michael
