[Gnuplot-bugs] '\\' between enhanced/noenhanced postscript

[Shigeharu T. <sh...@ie...>]

----------------

In Postscript terminal, '\\' is treated with some differences
between enhanced and noenhanced. In PS_put_text() of 
term/post.trm, it will be '\\' + '\\' and may be fine in PS file.
On the oter hand, ENHPS_put_text() puts

1) '\\' if the next character is '\\' or '(' or ')',
2) '\\' + octal if the following 3 charcters are octal,
3) none otherwise.

I think the behavior 3) is not so good. The following patch for
src/term.c of gnuplot-4.0.0 solves it, but it may cause other
problem (I don't know well).
