I am sure this is easy for people who are good at regexps but I'm
failing with it.? The situation is that I have hundreds of lines of
Ukrainian translations of some English. They contain things like this:
1"? ????? ????, ???? ?????"2"???? ??????? ???????
??????"3"? ?????
(???????) ????, ???? ????? (??????)"4"? ?????(-??) ?????, ????
????????
???????"5"? ?????/?? ????, ???? ?????/??"6"? ?????\\???????
????, ????
???????\\????????."7"? ????????(??) ????, ???? ?????(??)"
Using dput():
tmp <- structure(list(Text = c("? ????? ????, ???? ?????",
"???? ???????
??????? ??????", "? ????? (???????) ????, ???? ????? (??????)",
"?
?????(-??) ?????, ???? ???????? ???????", "? ?????/?? ????, ????
?????/??", "? ?????\\??????? ????, ???? ???????\\????????",
"?
????????(??) ????, ???? ?????(??)" )), row.names = c(NA, -7L), class =
c("tbl_df", "tbl", "data.frame" )) Those show four
different ways
translators have handled gendered words: 1) Ignore them and (I'm
guessing) only give the masculine 2) Give the feminine form of the word
(or just the feminine suffix) in brackets 3) Give the feminine
form/suffix prefixed by a forward slash 4) Give the feminine form/suffix
prefixed by backslash (here a double backslash) I would like just to
drop all these feminine gendered options. (Don't worry, they'll get back
in later.) So I would like to replace 1) anything between brackets with
nothing! 2) anything between a forward slash and the next space with
nothing 3) anything between a backslash and the next space with nothing
but preserving the rest of the text. I have been trying to achieve this
using str_replace_all() but I am failing utterly. Here's a silly little
example of my failures. This was just trying to get the text I wanted to
replace (as I was trying to simplify the issues for my tired wetware): >
tmp %>%+ as_tibble() %>% + rename(Text = value) %>% + mutate(Text =
str_replace_all(Text, fixed("."), "")) %>% +
filter(row_number() < 4)
%>% + mutate(Text2 = str_replace(Text, "\\(.*\\)",
"\\1")) Errorin
`mutate()`:?In argument: `Text2 = str_replace(Text, "\\(.*\\)",
"\\1")`.Caused by error in `stri_replace_first_regex()`:!Trying to
access the index that is out of bounds. (U_INDEX_OUTOFBOUNDS_ERROR) Run
`rlang::last_trace()` to see where the error occurred. I have tried
gurgling around the internet but am striking out so throwing myself on
the list. Apologies if this is trivial but I'd hate to have to clean
these hundreds of lines by hand though it's starting to look as if I'd
achieve that faster by hand than I will by banging my ignorance of R
regexp syntax on the problem. TIA, Chris

Chris,
Consider breaking up your task into multiple passes.
And do them in whatever order preserves what you need.
First, are you talking about brackets as in square brackets, or as in your
example, parentheses?
If you are sure you have no nested brackets, your requirement seems to be that
anything matching [ stuff ] be replaced with nothing. Or if using parentheses,
something similar.
Your issue here is both sets of symbols are special so you must escape them so
they are seen as part of the pattern and not the instructions.
The idea would be to pass through the text once and match all instances on a
line and then replace with nothing or whatever is needed. But there is no
guarantee some of your constructs will be on the same line completely so be
wary.

Does this do it for you (or get you closer):
gsub("\\[.*\\]|[\\\\] |/ ","",tmp$Text)
[1] "? ????? ????, ???? ?????"
[2] "???? ???????\n??????? ??????"
[3] "? ????? (???????) ????, ???? ????? (??????)"
[4] "?\n?????(-??) ?????, ???? ???????? ???????"
[5] "? ?????/?? ????, ????\n?????/??"
[6] "? ?????\\??????? ????, ???? ???????\\????????"
[7] "?\n????????(??) ????, ???? ?????(??)"
