Hello all!
I need to replace many emoticons in a large xelatex-file. I have had the
intention to make a perl-filter like follows
while(<>){
s/\x3DD818DE/pix/emo01.jpg/g
etc etc
}
but already the search in BBEdit for the hexcode did not succeeded.
I made a file with two emoticons:
😘 🚕
Separated by spaces. The hexdump gave:
0000: 20 00 3D D8 18 DE 20 00 3D D8 95 DE 20 00 .=... .=... .
When you hex dump an open document from memory, you are seeing
the actual byte order as it is used by the computer. On Intel
machines, this is reversed from Unicode, so a space U+0020 will
dump as 20 00 as you see there.
I searched for the icons first. No success. Then I tried to find the
space. Apparently the space is 20 00. I searched for \x{2000} grep
turned on. Right? No success! There is something obvious I missed.
When using escapes in the Find window, use the actual Unicode
code point. So, search for \x{0020} and you will get your
desired result.
The code points of the icons I found with "Special Characters" under the
Menu "Edit":
Kiss: U+1F618 (U+D83D U+DE18) UTF-8: F0 9F 98 98
Taxi: U+1F695 (U+D83D U+DE95) UTF-8: F0 9F 9A 95
My Question: how to find with hexcode in general and these icons in
special.
BBEdit stores everything as UTF-16, so you won't be able to find
what you're searching for by using U+1F618. Instead, try
searching for the combining code points and see if that works:
\x{D83D}\x{DE18}, for example.

Someday I'll look back on all this and laugh... until they
sedate me.
