Thank you very much @Snowbird

You have cleared up my question. I had begun to suspect that that might be the case. For the Pāli course I’ve just started they’re using materials of varying ages, hence my confusion. 
Obstacle/challenge number 1 overcome… only 10,000 more to go

I don’t know how to take screen shot
but here it is long hand… I get an error message of
https://www.ancient-buddhist-texts.net/download/index.htm/Input#:~:text=404,on%20this%20server! this is error 404 Not Found
When I tried to download the fonts as per links in the website itself (relevant section copied below in italics), then when I tried to open them Id get this message;" Compressed folder error. Windows cannot complete the extraction. The destination file could not be created."
The fonts are embedded in the html also, via CSS @FontFace, but if you have any difficulties reading the documents you may need to download and install the ITM_TMS_UNI font (128 KB), which comes in 4 styles - Regular, Italic, Bold, and Bold Italic.
The css files define the Unicode fonts in this order: ITM_TMS_UNI, ITM_TFY_UNI, ITM_Verajja, “Gandhari Unicode”, “Times Ext Roman”, “Indic Times”, “Arial Unicode MS”, Tahoma, Gentium, serif. This is a descending order: if ITM_TMS_UNI is installed it will show that font, if it is not, but ITM_TFY_UNI is installed it will show that font, and so on down. Only the ITM series of fonts will display the metrical markings and all the Romanised Sanskrit letters correctly.
To view the character set and find out more about the font, please read the ITM_TMS_UNI-reference.pdf (444 KB). The above fonts (ITM & Unicode) are being distributed under the GNU GENERAL PUBLIC LICENSE, a copy of which can be read here.
Unicode Input-Programme
There is also a Unicode input-programme (385 KB)
Thanks once again for helping out and making it so easy to understand and use- much appreciated

PS for those who may not be familiar with the site at SuttaFriends, it is really great and has lots of wonderful resources.
