Doug noted earlier that the implementation supports 0x200C (ZERO WIDTH
NON-JOINER) and 0x200D (ZERO WIDTH JOINER). Not supported (along with
ZWSP) is WORD JOINER 0x2060. I assume this means that neither will ever
occupy any rendering space.
What's the effect of ZWNJ and ZWJ on ligatures? Will
There are really 2 questions here:
- How do I manipulate a BufferedImage without interfering with its
ability to be accelerated under the covers?
- Is there a type of image that lives in hardware accelerated memory and
to which I can write directly to its pixels?
To answer the first question,
I assume this means that neither will ever occupy any rendering space.
It will likely depend on the font. If the font maps it to a zero width
glyph then yes
But if the font doesn't map it, and since JDK doesn't treat it
specially, then it'll end up mapped to the missing glyph
just like *any*
