Fråm a Nårdik pørspæktiv its nåt riily ænyÞing batt än ædjustment. I assume the same could be applied for German speakers, although their range of local additions to the Latin alphabet differs somewhat from ours.

That's really just using slight modifications, using our own perception of what English sounds to us though. I expect it would look quite alien to the rest of the World, if the Brits started doing it based on their own sense of what written english should look like.

While spoken and written English differ quite a lot, I suspect that to be one of the reasons as to why English has been so successful as a a Global trade language (I'm deliberately ignoring the Brittish Empire here). If English hadn't been standardized, and all English-speaking countries had their own separate written English based on their local dialects, the situation would be quite different.

Mark Twain: A Plan for the Improvement of English Spelling:

For example, in Year 1 that useless letter 'c' would be dropped to be replased either by 'k' or 's', and likewise 'x' would no longer be part of the alphabet. The only kase in which 'c' would be retained would be the 'ch' formation, which will be dealt with later. Year 2 might reform 'w' spelling, so that 'which' and 'one' would take the same konsonant, wile Year 3 might well abolish 'y' replasing it with 'i' and Iear 4 might fiks the 'g/j' anomali wonse and for all. Jenerally, then, the improvement would kontinue iear bai iear with Iear 5 doing awai with useless double konsonants, and Iears 6-12 or so modifaiing vowlz and the rimeining voist and unvoist konsonants. Bai Iear 15 or sou, it wud fainali bi posibl tu meik ius ov thi ridandant letez 'c', 'y' and 'x' -- bai now jast a memori in the maindz ov ould doderez -- tu riplais 'ch', 'sh', and 'th' rispektivli.
