demo/enhancedtext.dem

[Petr M. <mi...@ph...>]

When trying demo/enhancedtext.dem, I've found few bugs:

1.
Enhanced text in x11 terminal is ignored for subscripts and
superscripts:

set term x11 enhanced
set label 3 "{/Symbol abcd} e^{/Symbol abcd} g_{/Symbol abcd}" at 0,-6
plot x


2.
png terminal should ignore cases in font names:
set term png enha font "arial.ttf"
set out 'a.png'
load '/usr/share/doc/packages/gnuplot/demo/enhancedtext.dem'

It prints errors, while one would expect "/Symbol" to be the same as
"/symbol":

gdImageStringFT: Could not find/open font while printing string =EF=BF=BDwi=
th font Symbol
gdImageStringFT: Could not find/open font while printing string 0 with font=
 Symbol
gdImageStringFT: Could not find/open font while printing string  with font =
Symbol
gdImageStringFT: Could not find/open font while printing string m with font=
 Symbol
gdImageStringFT: Could not find/open font while printing string m=3D(p/2) w=
ith font Symbol
gdImageStringFT: Could not find/open font while printing string 1/2 with fo=
nt Symbol


3.
In "help x11":
    set term x11 enhanced font "arial,15"
    set title '{\=3D20 Big} Medium {\=3D5 Small}'

    set term x11 enhanced font "terminal-14"
    set title '{\=3D20 Big} Medium {\=3D5 Small}'

=3D> I think those "\" should be "/"


Ethan, can you please have a look?
