Some DOIs have parentheses or other special characters...

... which causes the shell to bark.

Examples in 10.1044/1092-4388(2010/09-0106) 10.1044/1092-4388(2009/07-0280) 10.1044/1092-4388(2007/028) . Could be circumvented by having the option to run the bot via PMCID, as per https://github.com/erlehmann/open-access-media-importer/issues/44 .

Error is:

Problem is not the shell, but esearch. For doi:10.1044/1092-4388(2010/09-0106) the esearch result URL is http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=pmc&term=10.1044/1092-4388(2010/09-0106)[doi], which contains nothing of value.

“Entrez processes all Boolean operators in a left-to-right sequence. Enclosing individual concepts in parentheses changes this priority.” – http://www.ncbi.nlm.nih.gov/books/NBK3837/#EntrezHelp.Using_Boolean_Operators

[erlehmann]

Can we delegate this?

[Daniel-Mietchen]

I lowered the priority to "Nice to have", since none of the publishers currently foreseen for the whitelist (cf. https://github.com/erlehmann/open-access-media-importer/issues/57 ) use such DOI schemes.
