# Non-English characters in URLs with Biblatex-Chicago + Biber

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

@misc{RussianEmpire.1855,
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
\documentclass{article}

\usepackage{fontspec}
\usepackage[russian,british]{babel}
\newfontfamily\russianfont[Script=Cyrillic]{CMU Serif}
\usepackage[CJK, Cyrillics]{ucharclasses}
\setTransitionsForCyrillics{\russianfont}{}
\usepackage{csquotes}
\usepackage[labeldate,backend=biber]{biblatex-chicago}

\begin{filecontents}{bibliography.bib}
@misc{RussianEmpire.1855,
author = {Russian Empire},
year = {1855},
title = {Treaty of Shimoda},
url = {https://ru.wikisource.org/wiki/Симодский_договор_с_Японией_(1855)},
}
\end{filecontents}

Output:

• You should make a complete example. This would make tests much easier. – Ulrike Fischer Oct 4 '16 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 – Amorok Oct 4 '16 at 17:29
• Added minimal working example illustrating the problem. – Arc Oct 4 '16 at 18:04
• 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. – PLK Oct 4 '16 at 19:35
• Thank you for the reply, PLK. Good to have it narrowed down. :) – Arc Oct 16 '16 at 19:02

Biber 2.7 introduces a new option to disable URI encoding of URLs, use the switch

--nouri-encode


when you compile with Biber.
