It may occur that the specific installed font is not available for the Text Box and Edit options in FineReader 15 PDF Editor. Nevertheless, if you copy the text from any other text editor and paste it on the needed page using the Text Box option, the font name will be displayed in the square brackets.
This happens due to the format of the font. The installed TrueType fonts (*.ttf) are available for both options, while the OpenType fonts (*.otf) are not available. Thus, if the font is not available, please check the type of it.
As a temporary solution, we would recommend you copying the text from any other text editor and paste it on the needed page using the Text Box option.
