Sure, and so too is omitting an accent mark or diaeresis.  But—alas!—you’ll
never convince most monoglot anglophones of that, the ones who keep wanting to
strip them from résumé, façade, châteaux, crème brûlée, fête, tête-à-tête, 
à la française, or naïveté, not to mention José, jalapeño, the erstwhile
American Secretary of State Federico Peña, or nearby Cañon City, Colorado, 
where I have family.  I think œnonlogy has survived solely on its rarity, 
and the Encyclopædia Britannica is that way because the ligat(ur)ed letter
is in their actual trademark.

Cell phone users sending text messages have long suffered the grievous
injuries to their language(s) that naked ASCII imparts, but this is
nothing like the crossdressing nightmare called Greeklish, also variously
known as Grenglish, Latinoellinika/Λατινοελληνικά, or ASCII Greek.

    http://en.wikipedia.org/wiki/Greeklish

    [...] The reason for this is the fact that text written in Greeklish
    is considerably less aesthetically pleasing, and also much harder to
    read, compared to text written in the Greek alphabet. A non-Greek
    speaker/reader can guess this by this example: "δις ιζ χαρντ του
    ριντ" would be the way to write "this is hard to read" in English
    but utilizing the Greek alphabet.

I especially enjoy  George Baloglou’s "Byzantine" Grenglish, wherein:

    Ὀδυσσεύς    => Oducceus    instead of Odysseus
    Ἀχιλλεύς    => Axilleus    instead of Achilleus
    Σίσυφος     => Sicuphos    instead of Sisyphus
    Περικλῆς    => 5epiklhs    instead of Pericles
    Χθονός      => X8onos      instead of Chthonos
 Οι Ατρείδες    => Oi Atpeides instead of the Atreïdes

Terrible though the depredations upon the French language that may
have been committed by ASCII, surely these go even further. :)
