That's not really a Thai character, right? It's way too many bytes! It must be an intentional repetition of stacking diacritics. Some of the ones in that Google result page are 21 bytes.


   $ echo ก็็็็็็็็็็็็็็็็็็็ | hexdump
   0000000 e0 b8 81 e0 b9 87 e0 b9 87 e0 b9 87 e0 b9 87 e0

Something I wondered once: If one were to have a go at sanitizing Unicode input (e.g., for a forum), what would be a sensible limit on the number of diacritics to allow, without interfering with languages that need them?


I love StackOverflow: http://stackoverflow.com/questions/11978912/how-to-protect-a...


Thanks. I'd asked on SO about Unicode sanitization before and got a very "brush off" answer. Seems I was asking the wrong question.


Yep. With the diacritics spaced out:

     ก ็ ็ ็ ็ ็


looks like this is the unicode in html

ก ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็ ็


Yes, it is "THAI CHARACTER KO KAI" (U+0E01), plus 20 occurrences of the non-spacing mark "THAI CHARACTER THAI CHARACTER MAITAIKHU" (U+0E47).


It's odd, but I think the HN title has only 5 of those marks. Does HN code limit the stacking?


Indeed, pasting from the google input and investigating it's a single U+0E01 ก (THAI CHARACTER KO KAI) with 20 U+0E47 ็ (THAI CHARACTER MAITAIKHU), a diacritic.


It's definitely an intentional repetition of stacking diacritics. ก็ has a meaning in Thai, but not ก ็ ็ ็


It's 2 characters.
