how to do chars mapping

[mo-han]

i have a prefered mapping setting:

    char_map = {
        '\\': '⧹',  # U+29F9 (big reverse solidus)
        '/': '⧸',  # U+29F8 (big solidus, permitted in Windows file and folder names）
        '|': '￨',  # U+FFE8 (half-width forms light vertical)
        ':': '꞉',  # U+A789 (modifier letter colon, sometimes used in Windows filenames)
        '*': '∗',  # U+2217 (asterisk operator)
        '?': '？',  # U+FF1F (full-width question mark)
        '"': '″',  # U+2033 (double prime)
        '<': '﹤',  # U+FE64 (small less-than sign)
        '>': '﹥',  # U+FE65 (small greater-than sign)
    }

can i do this with f2? how?

it can be achieved with multiple f2 -s -f -r commands, each time for one single char.
but that's kind of tedious.

@mo-han This functionality does not exist currently. How would you prefer to achieve this?

[mo-han]

maybe let f2 load a json file and get config from it.
but this might require to add a lot of code, i'm not sure if it's worthy.

After looking into it a bit more, you can achieve this with the chaining feature:

f2 -f '.*' -r '{f}{ext}' -f '\|' -r '￨' -f ':' -r '꞉' -f '\*' -r '∗' -f '\?' -r '？' -f '"' -r '″' -f '<' -r '﹤' -f '>' -r '﹥'

The initial -f and -r pair selects all the files in the directory and retains the same name, while subsequent pairs finds each target character and replaces them with your preferred character. You only need to escape the characters that are significant in regex.
