Several of the locales still do not use 

copy "iso14651_t1"

but create their collation rules from scratch.

It is better to first use iso14651_t1 and then apply only the changes
necessary.

This patch does this for the th_TH locale (Thai).

I made it to agree as much as possible with the rules from CLDR (see:
https://github.com/unicode-org/cldr/blob/main/common/collation/th.xml).

It seems to be impossible to follow the CLDR rules

  &[before 1]๚<ฯ # should be "variable"

and

  &๛<ๆ # should be "variable"

exactly though. These ask for a primary difference in punctuation
characters whose primary weight should be "IGNORE". But using a
secondary differnence instead still sorts the test data correctly and
the previously used collation in th_TH used tertiary differences for
these characters.

There was old localedata/th_TH.in test data in TIS-620 encoding which
was not used (it was not in the localedata/Makefile). I converted this
to UTF-8 and moved it to localedata/th_TH.UTF-8.in and added it to
localedata/Makefile.

Using the existing collation rules in the th_TH locale did not sort that
test file completely correct, I think my new collation rules based on
iso14651_t1 are better.

I see a lot of undecodable byte sequences which consist of "\340\270?"
and "\340\271?".

In the localedata/th_TH.in file, which the patch removes?

Like this:

index cc93d1f264..0000000000
--- a/localedata/th_TH.in
+++ /dev/null
@@ -1,178 +0,0 @@
-@@@@@
-0000
-10 litre
-10 litre (10 <C5>Ե<C3>)
-10 litre (<F1><F0> <C5>Ե<C3>)
...

?

This file was in TIS-620 encoding.

I converted it to UTF-8 an moved it to th_TH.UTF-8.in.

You are right, it seems to be displayed like that in other places.

But that seems to be a problem in how Gnus/Emacs display the patch.

I'll attach the exact same patch again here with disposition
“attachment” instead of “inline”:

Nope.  The patch itself broken.

FWIW, none of the bots in patchwork could apply the patch:

Unsurprisingly, this is even worse.

Patch

From 12e751450e849ee7d4c8a969a1f7708da589c5ef Mon Sep 17 00:00:00 2001

Subject: [PATCH] Adapt collation in th_TH locale to use the iso14651_t1_common
 file and sync the collation with CLDR

Use old existing localedata/th_TH.in file (which was not used),
converted it to UTF-8, added to the Makefile and modified it a bit.
The existing th_TH collation did not sort that file completely
correct.
