    Error is:
    Duplicate entry 'en-361-smiles_C' for key 2 INSERT INTO mdl_tool_customlang (lang,componentid,stringid,original,master,timemodified,outdated,local,timecustomized) VALUES(?,?,?,?,?,?,?,?,?) [array ( 0 => 'en', 1 => '361', 2 => 'smiles_C', 3 => 'aliphatic carbon atoms', 4 => 'aliphatic carbon atoms', 5 => 1330189912, 6 => 0, 7 => NULL, 8 => NULL, )]

    Error in language pack in version 2.3 (2012081600) occurs too. Very sad for us.

    We're about to start looking at 2.3. I'll get this issue fixed as part of that.

    Just to explain what is going on here. There are actually two different strings here: smiles_c and smiles_C. You can see those are different. I can see those are different. MySQL thinks they are identical.

    However, it is probably not a great idea to have two language strings that differ only be upper/lower case, so I will fix this.

    Ah. Well of course in SMILES 'c' and 'C' have clear, and different, meanings. 'c' is aromatic (as in benzene rings); 'C' is aliphatic (straight chains). Which tells you what to call them to distinguish them for the SQL.

    Hi,

    Thanks for fixing this Tim. I was using get_string to fetch the human name for the SMILES character suffixing the character with 'smiles' and then passing it to get_string. I guess one way to fix this might be to prepend big_ onto an upper case character and convert it to a lower case character appending that to smiles and looking up the translation with get_string
