bug#8563: 24.0.50; TeX IM \aleph should insert math aleph, not Hebrew aleph

[Trent W. Buck]

When I select the TeX input method (^X^M^\TeX^M) then insert an aleph
(\aleph), it inserts a hebrew aleph (א, D790 HEBREW LETTER ALEF).

Since the TeX IM is probably being used for math (cf. a hebraic IM), it
should instead insert the math codepoint (ℵ, E284B5, ALEF SYMBOL).

The current behaviour caused a problem in IRC, because another user's
IRC client (xchat 2.8.6) assumed that hebrew should be rendered
right-to-left, so instead of aleph-null, he saw null-aleph.  This did
not happen when he was sent the ALEF SYMBOL codepoint.
