What Alt + number is a tick?
I looked up the number on the internet and it said it was Alt + 0252 but this just gives me an ü. What number do you have to type in to get a tick while holding the Alt Key?
Solution 1:
The tick mark which you referred to, i.e Alt + 0252 is only possible if you select the font as "Wingdings" as mentioned in this Link.
The Unicode value depends on the font which is present in the editor which you are using and the tick symbol is not available in normal text fonts other than "Wingdings" or similar ones which are symbolic fonts.
Solution 2:
The standard check mark ✓ [yes, the UK calls it a tick, US check] is U+2713 so presumably on Windows that would equate to alt+2713, confirmed by FileFormat.
Yet when I test it, on an rtf file it generates ઙ & in a txt file Ö - so there appears to be no consistency.
Solution 3:
By default, windows alt codes point to the ASCII (+ Extended) character map. So without making any changes to the system, you can use [ALT] [2] [5] [1] to get a √.
Refer to the above answers for required steps to generate a Unicode tick.
