unicodetype_db.h is a file that needs to be regened, but it not
|
|
particularly trivial to regen. For the first build of Python,
|
|
strip out any kind of unicode support that requires
|
|
unicodetype_db.h indiscriminately.
|
|
|
|
We are effectively restricted to ASCII characters with this change,
|
|
but it works.
