Looking for some gimmick that would hide all characters from a field except for those within a given Unicode range
I'm pretty illiterate in coding, so please be gentle. I'm looking for a piece of code that would hide all characters from a field except for those within a given Unicode range. E.g., suppose the field has this input: abc 15 kg and 47 mm. If I decide on the Unicode range as from U+0030 to U+0039 (which is only ten digits), the output would be 1547, because the Latin letters and the space are outside of my Unicode range. Can it be done? I'll appreciate any help.
