1 converting between character sets
2
3 * overview
4
5 Since Malete can represent both record and index data as plain text files,
6 standard tools like
7 > http://www.gnu.org/software/recode/recode.html recode
8 or
9 > http://www.gnu.org/software/libiconv/ iconv
10 can be used for character set conversion.
11
12 This can also be used to conver WinIsis or wwwisist files via
13 > CDS cds import/export.
14
15
16 * example
17
18 To convert the standard WinIsis cds database to malete as is,
19 without any character set conversion, use
20 $
21 malete cdsimp -No850 cds
22 $
23
24 Create a textual representation of the index by
25 $
26 malete qdump cds 2>cds.mqt
27 $
28
29 Convert the textfiles to UTF-8 use
30 $
31 iconv -f CP850 -t UTF-8 <cds.mrd >cds.mrd-u
32 iconv -f CP850 -t UTF-8 <cds.mqt >cds.mqt-u
33 $
34
35 Replace the Malete database with the UTF-8 files
36 $
37 rm cds.mq? cds.mr?
38 mv cds.mrd-u cds.mrd
39 malete qload cds <cds.mqt-u
40 $
41
42
43
44
45 * notes
46
47 Conversions that do not change the byte count like for example
48 codepage 850 to Latin-1 can also be applied to IIF (ISO 2709) files.
49
50 This will not work for conversions like codepage 850 to UTF-8
51 which change the length of data.
