From the pdf sent by J. Patrick Harrington and
also the insight of Brian Schott on encoding
and Devon McCormick on font. I found sometimes
pdf can display correctly.
it use Helvetica font and latin1 encoding BUT
the mu in Patrick's mac is different from the
mu that I used in Linux. The following 2 mu looks
identical at least on my computer.
a.{~ 194 181 206 188
µμ
but their codepint are different
3&u: 7&u: a.{~ 194 181 206 188
181 956
Google said 181 is micro sign, 956 is Greek alphabet.
If 181 is used it looks fine, the following script use 181 for
mu
require'plot'
pd 'textfont Arial 19 Bold'
pd 'title T=12000K, lg=3.5: continuum + H-delta only (red) vs all lines (blue)'
pd 'ycaption Polarization (-Q/I) for µ = 0.1'
pd 'xcaption Wavelength (Å) --->'
pd */~ i: 10
pd'show pdf'
this script use 956 for mu
require'plot'
pd */~ i: 10
pd 'ycaption Polarization (-Q/I) for μ = 0.1'
pd 'show pdf'
I have updated plot package to handle extended latin1 characters
(code points from 128 to 255) more properly. So in short,
you can use acrobat built-in fonts and latin1 encoding to
display
_16]\ u:128+i.128

Characters above codepoint 255 require embedded font or other
adobe character set but I am not familiar with them except
Chinese Simplified and Chinese Traditional.
