I hope you'll forgive me, but I'm not willing to take your word for it about "jalapeno" being incorrect. I've emailed the editors of the OED, so if they reply I'll summarise here.
You needn’t have bothered. The OED entry for jalapeño is quite clear about this:

jalapeño, n.

Pronunciation: /hæləˈpiːnəʊ/ /-ˈpeɪn(j)əʊ/ /xalaˈpeɲo/
Forms: Also (erron.) jalapena. Pl. jalapeños.
Etymology: Mexican Spanish (chile) jalapeño Jalapa chilli: see ᴊᴀʟᴀᴘ n.
orig. and chiefly U.S.

Also jalapeño pepper. A very hot green chilli pepper, used esp. in Mexican-style cooking.

CITATION:

jalapeño, n.

Go ahead: look it up and see for yourself. It is quite simply erroneous to write jalapeño in English without the tilde, as the OED makes clear.

Then once you’ve tired yourself out on that one, you can look up words like Allerød, señor, animé, Boötes, café crème, fiancé, fiancée, caraña, goût, hijrī, façade, fête, fräulein, garçon, gâteau, ingénue, långbanite, Madrileño, mañana, mêlée, Möbius, Mohorovičić discontinuity, Muʿallaqāt, naïveté, Nescafé, nováčekite, omertà, pâté, pièce montée, piña colada, piñata, plaçage, Provençal, chèvre, curaçao, Einfühlung, Niçoise, Qualitätswein, Québecois, quinceañera, Rōjū, rubāʿī, sertão, smørrebrød, Štokavian, téléférique, tête-à-tête, torchère, tortilla española, Tuatha Dé Danann, Übermenschlichkeit, Únětician, vargueño, vicuña, Vinča, vis-à-vis, vṛddhi, Zuñi, and chef d'œuvre, all also in the OED, and all only in the spellings as I have given them here. While you’re there, you might also take note that they admit no valid spelling of résumé shorn of its diacritics.

Don’t go running to the OED for help in writing English poorly: they actually know how to spell. 😈

Back to Perl content: good luck with things like smørrebrød, since U+00F8 LATIN SMALL LETTER O WITH STROKE has no decomposition that will get you to o’s without the slashes; you need to go all the way to a full Unicode Collation comparison at the primary strength only before it counts as the same letter.
