Thanks for the new patch, that's looking nice. Now I was not able to
compile it as saslprep.h is missing from what you have sent...
There is for example this portion in the new tables:
+static const Codepoint prohibited_output_chars[] =
+{
+ 0xD800, 0xF8FF, /* C.3, C.5 */
----- Start Table C.5 -----
D800-DFFF; [SURROGATE CODES]
----- End Table C.5 -----
This indicates a range of values. Wouldn't it be better to split this
table in two, one for the range of codepoints and another one with the
single entries?
+ 0x1D173, 0x1D17A, /* C.2.2 */
This is for musical symbols. It seems to me that checking for a range
is what is intended.
