That's already on my to-do list. I am already in contact with Gihan
Dias. I am also working with some UTC members to expand the Sinhala
section of the Unicode standard. We plan to draw from SLS 1134 and will
send our feedback to the authors of SLS 1134 after we found the time to
research and discuss all the necessary details.

But it seems to me that you are talking about a possible future version
of the SLS 1134 standard.

I understand. The term "shall" in SLS 1134 probably means "MUST", not
But it doesn't change anything. The main point is still there: SLS 1134
does not require those 'computer systems' to check the fonts at
run-time. It only requires them to include one font that is SLS 1134

I don't understand this one.

I did exactly that before I wrote my comments yesterday. And the
sections you quoted were among the parts I re-read. How else could I
have remembered the SLS 1134:Part 2 terminology?

This confirms what I wrote yesterday.
It says that the one Sinhala font that is provided with the 'computer
system preloaded with Sinhala' (who claim SLS 1134 support and wish to
be certified as compliant) should have the specifications described in
It does *not* say that the 'computer system' should check the other
Sinhala fonts later installed to see if they have the specifications
described in the earlier sections.

This also confirms what I wrote yesterday.
It says that fonts (who claim SLS 1134 support and wish to be certified
as compliant) would need to choose one of the three different levels and
make sure they support that level according to the standard.
It does *not* say that any software should check fonts for level 1 (or
any other) level conformance before using them.
PS: I'm out of this. I believe I have proven my point that your claim
about operating system/rendering engine design was your personal
opinion, not what the SLS 1134 standard recommends. I don't have to
convince you personally. I never intended to.
