Legacy characters and corruption
The previous reply shows the problem of legacy characters (in http://dx.doi.org/10.1371/journal.pbio.1000481 - open up the PDF Table 1 if you want to verify ). Look at the text under "KD" It reads (μM)c. This means "micromolar" i.e. a concentration of 10-6 Molar. Try to cut and paste this from the PDF and you'll probably get
(mM)c
Any scientist would interpret this as "millimolar" - 1000X more concentrated. This could easily kill the organism, which might be you.
AMI-pdf2svg is able to convert characters heuristically.
The raw SVG shows:
<text stroke="none" fill="#000000" clip-path="url(#clipPath9)" svgx:fontName="NPJKJN+AdvP697C"
svgx:charName="m" svgx:charCode="956" svgx:hexCode="3bc" x="331.086" y="109.232"
font-size="6.485" font-family="TimesNewRoman" font-weight="normal" id="text8722"
svgx:width="750.0" xmlns:svgx="http://www.xml-cml.org/schema/svgx">μ</text>
Because these fonts are undocumented I have created an equivalence table by hand - very boring. It maps character "m" in Font "AdvP697C" to character "0x03bc" which is "mu"
However this has to be done for every font. For the "minus" in s-1 we have
<text stroke="none" fill="#000000" clip-path="url(#clipPath1)" svgx:fontName="NPJKLP+AdvP7DA6"
svgx:width="833.0" x="280.403" y="106.114" font-size="4.931" font-family="TimesNewRoman"
font-weight="normal" id="text8708" xmlns:svgx="http://www.xml-cml.org/schema/svgx">2</text>
We do not have a converter for this font and so its (legacy) "codepoint" "2" is translated into the wrong character. (I thought I trapped unknown fonts - will have to check). Any other tool will select "2".
