Problem with update biblatex

Question

Recently I reinstalled Windows 10 on my computer, so I reinstalled texlive, texstudio, etc.

I had a bibliography style which was perfect thanks to this forum but yesterday when I compiled, I discovered with horror that my bibliography style had changed.

Indeed, as you can see with pictures, there are not bracket for authors and byeditor's initial, besides citation style and the label are in small caps whereas I would like in lower case. I don't understand why it's changing.

Before update and with my last configuration I had: Now I have that:

And to success to compile I have to replace firstinit by giveninits

Do you have an idea? I guess it's cause to update of biblatex but I'm a too bad in code to know where the issue is ?

Thanks, PS: sorry for my big MWE ...

Edit 1: I have just discovered a last problem which appears for certain cases, how it appears with you:

@Book{roman.roman1997,
  title =     {Histoire de la Gaule (VI\ieme{} s. av. J.-C. -- I\ier{} s. ap. J.-C.). Une confrontation culturelle},
  publisher = {Fayard},
  year =      {1997},
  author =    {Daniele Roman and Yves Roman},
  pagetotal = {791},
  address =   {Paris},
  owner =     {Axel},
}

This problem of initial appears in some other cases while my bibliography contains more than 500 entries which works well. Do you have an idea? I try to recreate entry, remove accent, change title etc. Nothing works !

Answer 1

If you use Biber you will need the following redefinition of name:family-given

\renewbibmacro*{name:family-given}[4]{%
  \ifuseprefix
    {\usebibmacro{name:delim}{#3#1}%
     \usebibmacro{name:hook}{#3#1}%
     \ifdefvoid{#3}{}{%
       \ifcapital
         {\mkbibnameprefix{\MakeCapital{#3}}\isdot}
         {\mkbibnameprefix{#3}\isdot}%
       \ifprefchar{}{\bibnamedelimc}}%
     \mkbibnamefamily{#1}\isdot
     \ifboolexpe{%
       test {\ifdefvoid{#2}}
       and
       test {\ifdefvoid{#4}}}
       {}
       {\bibnamedelimd\bibopenparen}%
     \ifdefvoid{#2}{}{\mkbibnamegiven{#2}\isdot}%
     \ifdefvoid{#4}{}{\ifdefvoid{#2}{}{\bibnamedelimd}\mkbibnamesuffix{#4}\isdot}%
     \ifboolexpe{%
       test {\ifdefvoid{#2}}
       and
       test {\ifdefvoid{#4}}}
       {}
       {\bibcloseparen}}
    {\usebibmacro{name:delim}{#1}%
     \usebibmacro{name:hook}{#1}%
     \mkbibnamefamily{#1}\isdot
     \ifdefvoid{#4}{}{\bibnamedelimd\mkbibnamesuffix{#4}\isdot}%
     \ifboolexpe{%
       test {\ifdefvoid{#2}}
       and
       test {\ifdefvoid{#3}}}
       {}
       {\revsdnamepunct\bibopenparen}%
     \ifdefvoid{#2}{}{\mkbibnamegiven{#2}\isdot}%
     \ifdefvoid{#3}{}{\ifdefvoid{#2}{}{\bibnamedelimd}\mkbibnameprefix{#3}\isdot}%
     \ifboolexpe{%
       test {\ifdefvoid{#2}}
       and
       test {\ifdefvoid{#3}}}
       {}
       {\bibcloseparen}}}

Aside from the changes already applied by cfr (those are also explained in Biblatex 3.3 name formatting) we need to change the \ifblanks to \ifdefvoid (this is contrary to what you currently see in version 3.3, but \ifempty had some problems and will be removed).

Because name handling has changed so drastically, the old code and current BibTeX code needs to use \ifblank, while current Biber needs \ifdefvoid.

Answer 2

The following seems to work. This uses Latin Modern since I doubt very much that I have a font called Times New Roman complete with small-caps etc.

I had to switch to the Biber backend to get this to work. Without that, Biblatex refused to countenance a UTF-8 encoded database file, which you presumably want in this case.
