Is there any way to keep the URLs in the same form they are saved within the .bib files when using biblatex-chicago with Biber? For instance, the entry

 author = {Russian Empire},
 year = {1855},
 title = {Treaty of Shimoda},
 url = {https://ru.wikisource.org/wiki/Симодский_договор_с_Японией_(1855)},

results in the following output:

While there certain are benefits to converting the link itself, this sort of output in the footnote makes it both ugly and difficult to re-enter the link when reading a printed copy. How would one proceed about to receive the output along the lines of "https://ru.wikisource.org/wiki/Санкт-Петербургский_договор_с_Японией_(1875)"?

Minimal working example:

%!TEX program = xelatex

\newfontfamily\russianfont[Script=Cyrillic]{CMU Serif} 
\usepackage[CJK, Cyrillics]{ucharclasses}

 author = {Russian Empire},
 year = {1855},
 title = {Treaty of Shimoda},
 url = {https://ru.wikisource.org/wiki/Симодский_договор_с_Японией_(1855)},


Cyrillics support test: Тест\\

  • You should make a complete example. This would make tests much easier. Commented Oct 4, 2016 at 16:21
  • Maybe when you copy and past, you (youre OS or whatever) change the encoding. Try a encoding-decoding software like asiteaboutnothing.net/c_decode-url.html

    biber URI encodes all URLS. Version 2.7, currently in development on Sourceforge, adds a new option --nouri-encode which disables URI encoding. This requires version 3.7 of biblatex, also in development.

  • Thank you for the reply, PLK. Good to have it narrowed down. :)
