specify character encoding (e.g. UTF-8)

[Akashdeep Kasaodhan]

Hi,

While writing to a file in Cache, is there a way to specify which character encoding (like UTF-8) the file takes?

Also, Is there is a default character encoding which all files take.

regards,

Akash

Default encoding depends on installation, in installations process, you should choose 8-bit or Unicode. While install Ensemble, you can't do so, every installations will be Unicode.

To check it, you can look at

w $system.Version.IsUnicode()

or by letter U in Build number in $zv

Cache for UNIX (Apple Mac OS X for x86-64) 2016.1 (Build 646U) Fri Feb 5 2016 13:21:22 EST

and you can get actual current coding page by command

write $$GetIO^%NLS()

UTF8

If you need to control in which coding page will be written file, you may use %Stream.FileCharacter and it's TranslateTable property

    set fs=##class(%Stream.FileCharacter).%New()
    set fs.Filename="/tmp/temp.txt"
    set fs.TranslateTable="UTF8"
    do fs.Write("Caché")
    do fs.%Close()
    set sc=fs.%Save()

On your OPEN command's mode parameters, use the "K" letter code or the /TRANSLATE and /IOTABLE keywords. See http://docs.intersystems.com/cache20152/csp/docbook/DocBook.UI.Page.cls?KEY=GIOD_rmsseqfiles
