To perform a Compiled HTML Help (CHM) transformation, Oxygen XML Editor needs Microsoft HTML Help Workshop to be installed on your computer. Oxygen XML Editor automatically detects HTML Help Workshop and uses it.
Note: HTML Help Workshop might fail if the files used for transformation contain accents in their names, due to different encodings used when writing the .hhp and .hhc files. If the transformation fails to produce the CHM output but the .hhp (HTML Help Project) file is already generated, you can manually try to build the CHM output using HTML Help Workshop.

Changing the Output Encoding

Oxygen XML Editor uses the htmlhelp.locale parameter to correctly display specific characters of different languages in the output of the Compiled HTML Help (CHM) transformation. By default, the DITA Map CHM transformation scenario that comes bundled with Oxygen XML Editor has the htmlhelp.locale parameter set to en-US.

To customize this parameter, follow this procedure:

  1. Use the Configure Transformation Scenario(s) (Ctrl + Shift + C (Command + Shift + C on OS X)) action from the toolbar or the Document > Transformation menu.
  2. Select the DITA Map CHM transformation scenario and click the Edit button.
  3. In the Parameter tab, search for the htmlhelp.locale parameter and change its value to the desired language tag.
    Note: The format of the htmlhelp.locale parameter is LL-CC, where LL represents the language code (en, for example) and CC represents the country code (US, for example). The language codes are contained in the ISO 639-1 standard and the country codes are contained in the ISO 3166-1 standard.
