    <p>Given a corrupted file with mixed encoding (e.g. utf-8 and latin-1), how do I configure Emacs to "project" all its symbols to a single encoding (e.g. utf-8) when saving the file?</p> <p>I did the following function to automatize some of the cleaning, but I would guess I could find somewhere the information to map the symbol "é" in one encoding to "é" in utf-8 somewhere in order to improve this function (or that somebody already wrote such a function). </p> <pre><code> (defun jyby/cleanToUTF () "Cleaning to UTF" (interactive) (progn (save-excursion (replace-regexp "अ" "")) (save-excursion (replace-regexp "आ" "")) (save-excursion (replace-regexp "ॆ" "")) ) ) (global-unset-key [f11]) (global-set-key [f11] 'jyby/cleanToUTF) </code></pre> <hr> <p>I have many files "corrupted" with mixed encoding (due to copy pasting from a browser with an ill font configuration), generating the error below. I sometime clean them by hand by searching and replacing for each problematic symbol by either "" or the appropriate character, or more quickly specifying "utf-8-unix" as the encoding (which will prompt the same message next time I edit and save the file). It has become an issue as in any such corrupted file any accentuated character is replaced by a sequence which <em>doubles</em> in size at each save, ending up doubling the size of the file. I am using GNU Emacs 24.2.1</p> <pre><code>These default coding systems were tried to encode text in the buffer `test_accents.org': (utf-8-unix (30 . 4194182) (33 . 4194182) (34 . 4194182) (37 . 4194182) (40 . 4194181) (41 . 4194182) (42 . 4194182) (45 . 4194182) (48 . 4194182) (49 . 4194182) (52 . 4194182)) However, each of them encountered characters it couldn't encode: utf-8-unix cannot encode these: ... Click on a character (or switch to this window by `C-x o' and select the characters by RET) to jump to the place it appears, where `C-u C-x =' will give information about it. Select one of the safe coding systems listed below, or cancel the writing with C-g and edit the buffer to remove or modify the problematic characters, or specify any other coding system (and risk losing the problematic characters). raw-text emacs-mule no-conversion </code></pre>

    1. COBut is there a way to convert it automatically? Currently I select each offending character by hand, and perform a search and replace to delete it in the whole document. I plan to write a lisp function to automatize this, but I don't know how to automatize the list of offending characters (plus I would hope to do something more clever, such as é -> e, or something smarter projecting to accentuated characthers in utf-8...)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
