Including Sinhala and Thamil
on a website in Unicode

This is a project to include with Sinhala and Thamil Unicode, the text that appears on Ceylon and Sri Lanka Coins and Currency, on my websites coins.lakdiva.org and notes.lakdiva.org. I have with reasonable success, been able to do so despite not knowing to read, write or speak Tamil. The Sinhala & Tamil has been included in all of the BanknNote website except the local Political Fantasy Notes. It needs to be included for Decimal coins from 1870 to 2016, particularly the commemorative issues some of which have descriptive text in Sinhala and Tamil.

Questions:

Can they be written as it appears on currency notes with some optional Unicode text, script or font definition within the HTML ?.
Are there any changes needed to Unicode character set, or can issue be resolved within it's implementation. i.e. Improve default font implementation used by Windows, Chrome etc

Answers: By using font UN-Abhaya I can write Sinhala දා as required for රුපියල් දසදාහයි
By using font Lohit-Tamil-Classical I can write Tamil னா as required for பதினாயிரவ் ரூபாய்

Is it possible to make an included script file redefining the default fonts, for each of these languages, both regular and bold, so I can overlay the defaults and don't need to do a explicit
<span title="transliteration" style="font">Text in Unicode</span>
call each time I use Sinhala or Thamil within that document.

Although with these changes of font text appear as required on Screen, any printout is Not WYSWYG and defaults to regular font using Chrome and probabaly most other Browsers. Need to use Chrome Screenshot extention save as PDF and then print the PDF.

On these same lines the 18th century Arabic letters found on some Lankan coins and Currency is written in Persian Nasta'leek font which is significantly different from the Naskh font used by default for shared Arabic Unicode ranges in HEX: U+0600-06FF; U+0750-077F; U+FB50-FDFF; U+FE70-FEFF; They may not have got independent Unicode allocation as modern usage is switching over to standard Arabic font.

See also Discussion of Seal on Dutch Currency.

On the long term I would also like to develop font .ttf or .otf files to encode the 2nd century BCE to 2nd Century CE, Sinhala Brahmi See coin. As well as the 8th to 13th century Sinhala Nagari which appear on our coins and lot of inscriptions. Epigraphia Zeylanica uses modern Devanagari (Hindi) which looks very different to encode Nagari inscriptions found in Sri Lanka, to be able to be as close as practical to the way the text has been written.

The Symbols that appear in Indian and Lankan Punch mark coins also make an interesting collection. Similer symbol sets of other countries, have been allocated Unicode slots.

Chinese has been granted more than half the Unicode allocation. Many mostly western Ancient and Historic Scripts scripts have already been allocated. Can't we make a case for Sri Lanka to get few more slots to encode our ancient inscriptions as we find them written. In my opinion it is important to be able to represent text and symbols in ancient inscriptions in searchable Unicode so that they become part of digital knowledge.
