</div>

using tag-filename there are a few characters/symbols that don't show up in filename when the title is imported in itunes files (.m4a)

i have found that when i try to import filenames some symbols don't show up and the missing symbol loses its place in filenames

what i want to do is if a title has a symbol that doesn't transfer e.g' /' i would like it to be replaced simply with a '\_'

any help would be appreciated thanks

I think that the simplest way is to use the $validate() function.  
Enter your preferred composition of field variables but enclose the whole thing (to be sure) or just the %title% (if you are sure) in the $validate() function:  
e.g. $validate(%title%,\_)

Alternatively, you can devise your own rules with $replace().

And finally: there are characters for / that look like / but are in fact a different character e.g. ⁄

I have solved my issue with replace.

```
Original Replacement Unicode nr Unicode hex
/ ⁄ 8260 U+2044
: ː 0720 U+02D0
* • 8226 U+2022
? ‽ 8253 U+203D
" ″ 8243 U+2033
< ‹ 8249 U+2039
> › 8250 U+203A
| │ 9474 U+2502
\ ⁞ 8286 U+205E

```

Apart from Backslash () and star (\*) the replacement are very similar.

1. Build filename without losing special characters.

2. Extract info from filename (restore correct characters).
