If I run cat("\U001F615") on the command line in RStudio on my Mac, it shows the emoji. But if I knit it (Rmd) into a pdf, I get this error message:
! Package inputenc Error: Unicode char \u8:😕 not set up for use with
LaTeX.
See the inputenc package documentation for explanation. Type H
for immediate help. ...
l.144 \end{verbatim}
Try running pandoc with --latex-engine=xelatex.
pandoc:
Error producing PDF Error: pandoc document conversion failed with
error 43 Execution halted
But if I do latex_engine: xelatex, I don't get an error message, but the knitted pdf still doesn't show the emoji. Can someone help me in how I can knit to PDF with Emoji displaying?
There is a LaTeX package that adds support for emoji here: https://github.com/alecjacobson/coloremoji.sty
I haven't had any luck installing it though, because it's not on CTAN yet and I'm a LaTeX noob!
Once it's installed, you can add something like this to your YAML header:
---
title: "Title"
author: "Me"
header-includes:
- \usepackage{coloremoji}
output:
pdf_document

I'm using rmarkdown in rstudio and want to knit to pdf. This works well, except for when I use kable. I'm using the following yaml and it used to work in the past, but now I had to reinstall R, Rstudio and MacTex and now it doesn't work anymore.
---
title: "example"
output:
pdf_document:
df_print: kable
latex_engine: xelatex
---
```{r}
cars
```
The error message I get is:
output file: example.knit.md
! LaTeX Error: Environment kable-table undefined.
Error: LaTeX failed to compile example.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See Study-1.log for more info.
Does anyone know how to solve this?
This is a bug of rmarkdown (against higher versions of Pandoc), which I just fixed on Github. Please try:
remotes::install_github('rstudio/rmarkdown')
Text is missing after convert this pdf to image(png or jpg), but there no any error log.
Use ImageMagick：
convert -density 150 -quality 100 "d:/t/pdf/fp.pdf" -alpha Remove "d:/t/pdf/5/fp.png"
Use Ghostscript (testing with version 9.23 and 9.25)：
gswin64 -dSAFER -dBATCH -dNOPAUSE -r300 -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -sDEVICE=jpeg -sOutputFile=D:\t\pdf\123.jpg D:\t\pdf\fp.pdf
Anyone know what the reason and how to solve it? Thx.

There are two CIDFonts (STSong-Light and AdobeKaitiStd-Regular) used but not embedded. This means that a substitute font must be used. When run through Ghostscript this produces the following transcript:

So you can see two fonts being substituted, and then a more concrete problem. Your PDF file executes an image operator inside a text block, which is illegal. However for me the output is apparently correct.
[EDIT]
There is some odd behaviour here. I downloaded the 64-bit release code last night and tried that, and I do see the error. The back channel transcript contains this :

The key part is "Can't process embedded font stream....' That's why your text is going missing.
When I run the same command line using the current HEAD of our Git repository I don't see this error, and the file runs to completion. So it looks like this was a bug which has been fixed.
You have two options;
1) If you don't mind building the code, clone our Git repository, open the Visual Studio solution file, allow VS to update it to your version, then build Ghostscript. Use that binary.
2) As you've already discovered, don't use SAFER. I should caution you that this is a potentially dangerous setup. As long as you are processing files which you created yourself you should be fine, but please don't use this setup to process random files from untrusted sources, you could be laying yourself open to attack.
[edit 2]
And here's a third option. With 9.25 we started shipping the Resource files with Windows, just as we do with Linux. I suspect that if you add -I"c:/program files/gs/gs9.25/Resource/Init" to the beginning of your command line, it will work even when -dSAFER is true.
BTW its useful to quote the messages from the back channel when you have a problem, it may not tell you much, but it has useful information for PostScript developers.
The missing text came back when I removed the parameter -dSAFER. I don't understand why; I can't find the reason in the Ghostscript documentation.
This is my final command line:
gswin64 -dBATCH -dNOPAUSE -r150 -sDEVICE=jpeg -sOutputFile=D:\t\pdf\6\fp%03d.jpg D:\t\pdf\fp.pdf
How can I change the font color in RMarkdown pdf output.
I did try doing, Roses are \textcolor{red}{red}, violets are \textcolor{blue}{blue}.
But this only worked for the very first line in the pdf document. Upon using the same subsequently, it outputs this error,
! File ended while scanning use of \#xdblarg.

I'm attempting to convert latex to pdf, using doxygen generated latex files. I am using Doxygen 1.8.7. However, I keep getting this error:
!LaTex Error: Unknown float option 'H'.

I've narrowed it down to a .tex file, which contains the following:

Where do I go from here? Am I right in saying that it's looking for an image that it can't find?
This does indeed seem to be an issue with the float package. I had the same problem. However, just adding EXTRA_PACKAGES=float didn't fix it for me. I finally found this page which describes a conflict between the fixltx2e package and the float package which generates this error about the unknown H option. So, I commented out line 11 where it says \usepackage{fixltx2e} in the doxygen generated tex file (called refman.tex for me). Then it converted to pdf without any further problems.
As the latex error says, it's not looping for an image it can't find, but rather encountered an option to a floating element it doesn't understand. The 'H' option for float placement forces a figure to appear exactly at the place it appears in the latex code and essentially not to float. It requires the "float" package.
Thus in order to get your code working, add the following to the preamble:
\usepackage{float}
I'm not sure how to tell Doxygen that this package is required so as to not have to touch the automatically generated latex files..
In fact according to the doxygen documentation here adding the following to your configuration file should do the trick:
EXTRA_PACKAGES=float
There's a discussion on the 'H' option over here and a rather detailed discussion on latex float placement in general here.
When i am issuing the command
pdf2swf japanese.pdf -o japanese.swf -f -T 9 -t -s storeallcharacters
conversion returns an error:

I have checked the path file for CMAP in adobe and it shows that I have Adobe-Japan1 CMAP under C:\Program Files\Adobe\Reader 10.0\Resource\CMAP.
Then what I tried so far is to download CMaps for PDF CJK Fonts in here
Download CMAP for Japan
and replaced what is under the path. I am looking everywhere for fonts 'HGTT_0, HGTT_1, F0' in the web but still no luck. I research more of the problem and found out this Japanese Font conversion problem, might have some information I missed? Please help me to understand, why is pdf2swf still report for a notice that It cannot find 'Adobe-Japan1' collection wherein I actually have it?
