[Dreiheller, Albrecht via Unicode]

Could someone please supply an example (web link ...) for usage of danda / double danda in Tamil?
Thanks, Albrecht

It's worse than that when a script uses characters primarily

associated with another script.  For example, to have any confidence

that my Tai Tham font will be used for U+0E4A THAI CHARACTER MAI

TRI or U+0E4B THAI CHARACTER MAI CHATTAWA placed on U+1A4B TAI THAM

LETTER A, I have to set the Thai bit, even though I only have four Thai

characters in my font.  (The other two are punctuation.)



Indic scripts (other than Devanagari) also use a few characters from another block. Specifically, two punctuation characters (from the Devanagari block)

  *   U+0964 DEVANAGARI DANDA
  *   U+0965 DEVANAGARI DOUBLE DANDA
are expected to be used with the non-Devanagari Indic scripts. Looking at the fonts Noto Sans Kannada and Noto Sans Tamil, the expected Unicode range bit is set for Kannada or Tamil, but not Devanagari, even though those fonts contain U+0964 and U+0965.
