I am using couchdb and couchapp on windows.
I'm working on an ongoing project of a professor https://github.com/Hypertopic/Tire-a-part. I'm currently trying to set up the app on my computer.
When I do:
couchapp push http://127.0.0.1:5984/tire-a-part
I get an error:
Traceback (most recent call last):

File "json\encoder.pyc", line 264, in iterencode
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 1:

My professor and my friends all have mac and don't have this problem.
After a few hours on the net trying to search for similar problems I understand that it is an encoding error but i don't understand what is not correctly encoded and what should I do.
Thanks
Edit: I have discovered the debug option of couchapp. It gives much more detail but i still don't really understand as it is my first time with couchapp and couchdb. This is the last part of the debug as i don't think the begining is important:

I compared this with what my friend got on mac and it is the exact same except for the [CRITICAL] line. after the 'vendordon't exist' couchapp put _design/Tire-a-part
It really seem it was an encoding error of 'é'. There were 2 files with 'é' in their name. After changing it to 'e' the push command work. The app don't work but that's a story for another day....
I don't have the answer, but I tried something: I started a Python3.5 command line, and declared a variable byte='\xe9' and then printed the variable with print(byte). As can be seen below, the 0xe9 byte looks like to be the é character:
$ python3.5
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> byte='\xe9'
>>> print(byte)
é
>>>
I'm not sure why Windows has problem with the é character but macOS works fine.
On Linux shell command-line, when I put the é character in a file and take a hex-dump of the file, I see that the é character is actually equal to c3 a9, notice that the 0a is the new-line or line-feed:
$ echo 'é' > file
$ cat file
é
$ hd file
00000000 c3 a9 0a |...|
00000003
Therefore, I think the problem is that the é character is encoded with one byte of 0xe9 rather than two bytes of 0xc3 0xa9.
I played around with Go to see where the e9 comes from and I notice that the Unicode for é is actually \u00e9 and it is corresponding the two bytes of \xc3\xa9 i.e. 0xc3 and 0xa9, as shown below. Therefore, on your Windows machine, somehow the Unicode is mixed up with the hexadecimal bytes.
I'm knitting some beamer slides in an RMarkdown script in Rstudio on a Windows 7 PC. The slides are in the directory
C:/me/slides/myslides.Rmd
I have a master bibliography that lives in
C:/me/bib/masterbib.bib
I cannot figure out how to link to the bibliography file from the RMarkdown document. Here's the YAML from my attempt:
---
title: "Slides"
author: "me"
date: "2016-12-20"
bibliography: C:/me/bib/masterbib.bib
biblio-style: "apalike"
output:
beamer_presentation:
citation_package: natbib
---
Here's the error:
! Undefined control sequence.
<write> \string \bibdata {C:\me\bib\masterbib}
l.174 \end{frame}
Error: Failed to compile Slides.tex. See Slides.log for more info.
In addition: Warning message:
running command '"pdflatex" -halt-on-error -interaction=batchmode "Slides.tex"' had status 1
Execution halted
I've tried a couple other ways to specify the directory for masterbib.bib, but none have worked. I would prefer to keep the masterbib.bib file where it is, and not make an extra copy in the C:/me/slides/ directory. Thanks for your help!
Edit
When attempting to pass the following into YAML (quoteed with forward slashes):
bibliography: "C:/LaTeXstuff/BibTexLibrary/BrianBib.bib"
I get a fatal error with log output:

when running autoscan 2.69 (2012 release) I got this error message. It is a simple error in the perl code. autoscan is part of autoconf.
I edited the file: /usr/bin/autoscan (only changed line 361) the modified version:
360 s/#.*//;
361 s/\$\{[^\}]*\}//g;
362 s/#[^#]*#//g;
This seems to get rid of the warning (future will be error) message.
I am trying to run Open Drone Map which I have cloned to an Ubuntu 15.04 server I have installed all the required libraries. After I execute the code:
perl ../OpenDroneMap/run.pl
from within the directory I have all the photos in I get this error:
: , or } expected while parsing object /hash at character offset 11081 (before " " Mantis i23" : 45.00\n...") at ../OpenDroneMap/run.pl line 36, <$fh> chunk1.
Any help or suggestions greatly appreciated. Let me know if you need to see the perl code that executes.

Update your version of OpenDroneMap, it looks like it has already been fixed.

I am facing a strange issue with getting the db2 version using db2ls.

It looks like db2ls is having issues when executed from a directory having spaces. Is this a known issue? I could not find any documentation for this. I am trying to circumvent this problem by using db2ls 2>/dev/null.
If there is a more efficient way please let me know.
http://www-01.ibm.com/support/knowledgecenter/SSEPGG_10.5.0/com.ibm.db2.luw.qb.server.doc/doc/t0023683.html
for DB2 installation paths it says
DB2 installation paths have the following rules:
Can include lowercase letters (a-z), uppercase letters (A-Z), and the underscore character ( _ )
Cannot exceed 128 characters
Cannot contain spaces
Cannot contain non-English characters
Reading statements like this are always a warning sign not to use spaces in paths in general. BTW, shell scripts don't play well with spaces in paths which is for me a good reason to avoid spaces in general.
