ucs-insert in query-replace?

ucs-insert in query-replace?

[Tom Roche]

Just now I was trying to unencode some email with lines like

> * =E2=88=80 target values v: (v > 0) || is.na(v)

I know that '=E2=88=80' == '∀', so I did (the keyboard equivalent of)

> M-x query-replace '=E2=88=80'

and attempted to then do ucs-insert (C-x 8 RET 'for all'), but got

> Command attempted to use minibuffer while in minibuffer

How to do this correctly, or to do what I want some other way?

TIA, Tom Roche <Tom_Roche@pobox.com>

(setq enable-recursive-minibuffers t)

1. As Jambunathan mentioned, to be able to use a command (e.g. `ucs-insert')
from the minibuffer, set `enable-recursive-minibuffers' to non-nil.  (You
probably want to do that only temporarily.)

2. Instead of using `ucs-insert' for each such character you want to replace,
you can use library `ucs-cmds.el' to automatically create individual commands
that insert the chars from the Unicode subsets that you actually use.  Using
such commands is instantaneous.  Using `ucs-insert' each time you want to insert
such a character is quite slow.

3. If in addition to #2 you bind the specific char-inserting commands that you
use often to key sequences, then to use them in `query-replace' you need not set
`enable-recursive-minibuffers' to non-nil.  Just hit the keys for those chars to
insert them anytime.

Library `ucs-cmds.el' is here:

There's also the TeX input method which can insert quite a few Unicode
characters.  "C-u C-\ TeX RET" to activate it, "C-h C-\ TeX RET" to
display the characters it can insert.
