\math or $ doesn't work.

\math or $ doesn't work.

[John Culleton]

I want to insert the string 8 1/2 x 11 in my
text. Here is my test file:
----------------------------
\starttext
\math{8^1_2} × 11 inch, 
\stoptext
----------------------------
I am using texlive 2014 mkiv.

I also tried this:
-----------------------
\starttext
8 1/2 × 11 inch, 
\stoptext
---------------------
The error message is the same:
-------------------------------
system          > tex > error on line 2 in
file /usr/local/active/hall/ftp/test.tex: String
contains an invalid utf-8 sequence ...

1     \starttext
2 >>  8 1/2 × 11 inch, 
3     \stoptext
4     
5     
----------------------------------------

Hi John,

me too (current version: 2014.05.21 22:04 ;-)) and both samples (above
and below) compile fine.

Are you sure that character encoding in your file is utf8?

I can cause this error message, but only after replacing character
encoding in file with ISO 8859-15.

BTW, your file is in /usr/local. I thought that in Unix there was no
place like /home :-).

I hope it helps,


Pablo

We are on the home stretch now. I added
\enableregime  [utf-8] 
as the first line of my
master file. Theoretically I don't need this for a
MKIV run but so much for theory.

 Everything works. But there is
something wrong with my math code. There is no
horizontal bar between the 1 and the 2.  I guess
I will study "The TEXbook" some more.

Just FYI, I keep personal stuff and also my
political articles in /home/safe but my
typesetting and index work goes in subdirectories
of:
/usr/local/active/
one for each project.

Thanks for your prompt and useful reply!

Hi John,

It is a good idea to read again The TeXBook, but actually I wonder why should TeX put a horizontal line between 1 and 2 in your code? 
What you are typesetting in mathmode is just 8 followed by 1 in exponent (uppserscript) and 2 in subscript, therefore there shouldn’t be any fraction bar between 1 and 2.

If the font you use has the character, what you want to typeset is the character U+00BD for 1/2 or, if you want to use mathmode, either of the solutions below (wtach the slight differences between the three versions):

\starttext
$8\tfrac{1}{2} × 11$ inch

$8\frac{1}{2} × 11$ inch

$8{1 \over 2} × 11$ inch

\stoptext

Indeed you can replace $…$ with \math{…}.

Best regards: OK
