[R] plain text in Chinese can not be set

[Jinsong Zhao]

Hi there,

The following code can produce the correct type face, however, the Latin 
character are displayed in GB1 font.

pdf("test_1.pdf", family = c("GB1"))
plot(1:10)
text(5,1, "\u4F60\u597D", font = 1)
text(5,2, "\u4F60\u597D", font = 2)
text(5,3, "\u4F60\u597D", font = 3)
text(5,4, "\u4F60\u597D", font = 4)
text(5,5, "is 'hello' in Chinese", font = 1)
text(5,6, "is 'hello' in Chinese", font = 2)
text(5,7, "is 'hello' in Chinese", font = 3)
text(5,8, "is 'hello' in Chinese", font = 4)
dev.off()

and the following code can reproduce the problem I reported in previous 
post:

pdf("test_2.pdf", font = c("GB1"))
plot(1:10)
text(5,1, "\u4F60\u597D", family = "GB1", font = 1)
text(5,2, "\u4F60\u597D", family = "GB1", font = 2)
text(5,3, "\u4F60\u597D", family = "GB1", font = 3)
text(5,4, "\u4F60\u597D", family = "GB1", font = 4)
text(5,5, "is 'hello' in Chinese", font = 1)
text(5,6, "is 'hello' in Chinese", font = 2)
text(5,7, "is 'hello' in Chinese", font = 3)
text(5,8, "is 'hello' in Chinese", font = 4)
dev.off()


I have read the related source code, i.e., devPS.c, the function 
"PDFfontNumber" seems to write the font number to pdf file. And I think 
it might not consider the coexistence of "family" together with "fonts" 
options in pdf(). But I do not have the ability to give a solution.

Regards,
Jinsong
