Other spell-checking language in MdCharm
To add another language in the spell checker of the markdown editor MdCharm in Windows or GNU/Linux, download the desired dictionary (*.oxt) of OpenOffice. Unzip it with e.g. 7-Zip (Windows) or e.g. Roller (GNU/Linux) and copy the aff– and dict-files to the folder “spellcheckdict” of the MdCharm installation.
