This is the crucial issue. And it’s unsolvable. If you use non-standard format for your name, you WILL have problems.
Many, many, many computer systems in many many places use software written by Americans, and many Americans have no concept that the rest of the planet exists.
According to their software:
All human beings have exactly one first name, one middle initial and one last name of less than 15 letters, in standard English alphabet.
All human beings have an address that fits on 2 lines, formatted as number, streetname, cityname, state. (example:All human beings live at 1234 Maple Street, nobody lives at Maplestrauss 1234 )
All human beings live in one of 50 places, each with a two-letter abbreviation.
All human beings have a telephone number formatted in exactly 3-3-4 digits.
So Beware!
If you use a non-standard format, there are times when it won’t work, and you will regret it.
An Anecdote:
When I travel to the US, I carry my foreign phone. (I purchase a package from my foreign phone company which gives me a temporary synchronization to Verizon in America, but leaves my number the same, so anyone back home can reach me with the usual number in their contacts.)
But this means that my phone number for Americans dialing me within America looks like this:
12-345-6-789-1234
Most web sites cannot handle this! (I couldn’t use Uber).
When I travelled during covid, I had to have a lab test done the day of the flight. I tried to give my number and home address (with its funny-looking, furriner format) to the covid-testing labs in the airport… Impossible! Their computers exploded, and I almost got kicked off the flights.
So my advice about changing your name is simple : Don’t do it!!
There will be problems with some businesses, and you may not know it till it’s too late. Some places may just change your funny-furriner-letter to a regular, red-blooded-'Merican letter, and it might well work in their local system. (Who is going to notice those 2 dots missing over the letter o?)
But that could cause huge problems later. Suppose documents from one place don’t match your name with documents at another place–such as your bank, the title deed on your house, the name on your passport, the IRS, etc.
Be careful.
