        "plain":"\nDisclosed is a method for the selective catalytic reduction of NO? in waste/exhaust gas by using ammonia provides by heating one or more salts of formula M?(NH?)?Xz, wherein M represents one or more cations selected from alkaline earth metals and transition metals, X represents one or more anions, a represents the number of cations per salt molecule, z represents the number of anions per salt molecule, and n is a number of from 2 to 12, the one or more salts having been compressed to a bulk density above 70% of the skeleton density before use thereof.\n"
    }

The raw text has a formula with the markup information as shown below, M<sub>a</sub>(NH<sub>3</sub>)<sub>n</sub>X<sub>z</sub>

However, some of the information is lost in normalized version of the text. M?(NH?)?X<sub>z</sub>

At a quick glance looks like it may be a Unicode issue, either displaying or printing. If it's displaying it may be the editor your viewing the file with. But it could also be the code printing the file in ASCII, which would print Unicode characters, with no ascii conversion, as question marks.
