Subject: 0008 Tex backslash
|
||
|
|
|
||
|
|
Version 3.1.20 contains an irritating bug when using latex that causes all
|
||
|
|
sorts of problems when the backslash is used. (The backslash is a common
|
||
|
|
character in latex that is used, among other things, to create a forced space
|
||
|
|
similar to the tilde character.) In the current version, 3.1.20, the next TWO
|
||
|
|
characters are skipped after a backslash. This can results in misspellings and
|
||
|
|
the file being incorrectly parsed. (For example, if the text contains the
|
||
|
|
sequence `\ $' math mode will not be entered until the matching $ which should
|
||
|
|
end it, resulting in the body of the text not being spell checked and the math
|
||
|
|
region being checked.)
|
||
|
|
|
||
|
|
Make sure to undefine NO8BIT and use a larger number for MASKBITS if you are
|
||
|
|
using iso character sets.
