273747 - Mislabeled preference option (graphic emoticons => superscript)

Status: RESOLVED WONTFIX

(Thunderbird :: Preferences, defect)

Description

[Ryan Reich]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041110 Firefox/1.0
Build Identifier: Thunderbird/1.0

The option "Display emoticons as graphics" in Edit/Preferences/Display is rather
misleading, as it has other side effects unrelated to emoticons.  For example,
enabling this option also causes Thunderbird to render text such as a^2 as a
superscript, which may not be desirable in cases like a^12, which results in
only the 1 being written superscript.  Either fix the behavior or change the
label, please.

So *that'* how you make that work!  I always have emoticons turned off, and 
couldn't figure out why I could never see the superscripting that other bugs are 
filed around.

I am seeing multiple digits be raised:
  x^1234567890  raises all ten digits
but:
  x^3.14        only raises the 3
  x^3a          doesn't raise anything


Are there any other rendering features besides superscripting that get turned on 
with that preference, to your knowledge?

Not true.


I think fixing this bug would overcomplicate the UI for almost no use. The only
option I see is to create a new pref (in this case, makes code larger and
probably slower) or to entirely remove the features. Marking WONTFIX (valid bug,
but decided against).

Yes, only minor ones:

- superscript (as discussed)
- +/-
- \f = formfeed (spoiler?)
