Put uppercase letters in curly brackets in a BibTeX database
/^\s*[^@%]/
Apply the search-and-replace rule to lines that start (^) with zero or more white spaces (\s*), followed by any character ([...]) that is *NOT* a "@" or a "%" (^@%).
s=<some stuff>=<other stuff>=g
Search (s) for some stuff and replace by other stuff. Do that globally (g) for all matches in each processed line.
\([A-Z][A-Z]*\)\([^}A-Z]\|},$\)
Matches at least one uppercase letter ([A-Z][A-Z]*) followed by a character that is EITHER not "}" and not a capital letter ([^}A-Z]) OR (|) it actually IS a "}", which is followed by "," at the end of the line ($).
Putting regular expressions in escaped parentheses (\( and \), respectively) allows to dereference the matched string later.
{\1}\2
Replace the matched string by "{", followed by part 1 of the matched string (\1), followed by "}", followed by the second part of the matched string (\2).
I tried this with GNU sed, only, version 4.2.1.

[^}A-Z]\|},$which was designed to match capitals like intitle = {an upper case letter A},has the disadvantage that it also matches A and B here:abstract = { lorem ipsum A,dolor sit amet wtf Cconsectetur adipiscing elit B,...}How to fix...?abstract = { lorem ipsum {A},dolor sit amet wtf {C}consectetur adipiscing elit {B},...}So after applying sed we have that:abstract = { lorem ipsum {{A}},dolor sit amet wtf {C}consectetur adipiscing elit {{B}},...}
