As told try to edit fonts.xml.Use xs++ to browse the fonts folder in your mob fs.Read the names of the installed fonts.Probably you will file 4 files.In my fs there are 4.@ preinstalled ones and 2 I installed with the different fonts.You can edit fonts xml with notepad.When you open it it is easy to understand what you have to change in order to work.Just change the font names and upload the file.If you want new fonts you have to find fonts that include english and Hebrew.Use windows pc fonts which you already are working with.Replace names in fonts.xlm and then upload fonts and fonts.xml to your phone.
