Colleagues,
OS: OS X
R: 2.10.1
I want a mu (µ) to appear in text that is created using a PDF device. However,
the µ does not appear as intended; instead, it is replaced by two dots. A
minimal example is:
> pdf("mu.pdf")
> plot(1,1, type="n")
> text(1,1, "\u3BC")
> dev.off()
The "text" command yields the following warning messages:
> Warning messages:
> 1: In text.default(1, 1, "μ") :
> conversion failure on 'μ' in 'mbcsToSbcs': dot substituted for <ce>
> 2: In text.default(1, 1, "μ") :
> conversion failure on 'μ' in 'mbcsToSbcs': dot substituted for <bc>
> 3: In text.default(1, 1, "μ") :
> font metrics unknown for Unicode character U+03bc
> 4: In text.default(1, 1, "μ") :
> conversion failure on 'μ' in 'mbcsToSbcs': dot substituted for <ce>
> 5: In text.default(1, 1, "μ") :
> conversion failure on 'μ' in 'mbcsToSbcs': dot substituted for <bc>
In contrast, when I use a quartz device:
> plot(1,1, type="n")
> text(1,1, "\u3BC")
The mu appears as expected, presumably indicating that the problem relates to
devices.
For various reasons, I would like to avoid using plotmath (expression). Thanks
for any assistance.
