Translations:UI and Help files Content Guide/4/en
From The Document Foundation Wiki
Some words have to be unique in your translation files otherwise it will break the product or risk data loss for the user. These terms are:
- Style names such as those that you can find in the sw/source/ui/utlui.po file
- Function names in Calc that you can find in the formula/source/core/resource.po file
- Math symbols that you can find in the starmath/source.po file. Note also that Math symbols must not contain spaces. For example the perthousand math symbol must not be translated per thousand or noelement must not be translated no element.
- Index entries in the online help such as <bookmark_value\>Editing;Help Files\<\/bookmark_value\>, even if they are not in the same files, as it will break the display of the index entry.
