Text units for letter-spacing are incorrect

[r12a]

For various reasons wherever a word needs to be broken in constituent characters in case of Latin script, Indian language words can and should be broken based on Akshara as given here for a case of Devanagari script here

As the W3C specification points to Unicode Text Segmentation (TR 29), it is observed that some of the browsers support it (e.g. Chrome and Firefox) whereas Microsoft Edge and Interner Explorer seems to break the words in individual characters.

It has been marked as basic as the Unicode Text Segmentation rules themselves need to be matured enough to cater to nuances of many languages that get written using Gurmukhi script. Some of the languages like Santali, require some special Nukta rules.

Also, in cases where there is wrong Akshara formation e.g. Consonant+Matra+Matra, the breaking seems to stack ill formed akshara into one set instead of clearly breaking it separate. This breaking behaviour needs to improve.
