Hello!

I need to construct unicode value, using a string variable containing hexadecimal value of a unicode symbol. How can I do it?

I. e., I have code:string="0420". I need to get u"\u0420" for printing cyrillic letter "Щ". I've constructed a new string "u"\u0420"", but it's still considered by BRAINscript just as a string and doesn't produce expected cyrillic letter.
How can I do it?

Dmitry,

Here is a very simple graph example on how you can declare a unicode escape string.

The code in the filter is just this:
unistring = u"\u0429"
emit unistring as "unicoded"

The output of the filter is a щ character.

Looking at your post I think you have extra quotes, unless thats just from your posting.

Is this what you needed?

Hi Timon!

Not exactly. Have a look at the attached example. I want to add the code (e.g.0420) as a variable value. But I can only create a string that "imitates" a real unicode escape string, but doesn't work as needed.

Dmitry,

Ah, I see. Unfortunately I don't think this will work for you, the way you want it.

One option, which I will see about getting an example of, is to use a Python Filter, instead of a standard filter. It should only need a few small lines of code to work. But there is not a direct brainscript way to do what you are attempting.

Timon

You can do this:

emit code, unescape(u"\\u"+code) as ucd_symb

The trick in this is the unescape function, which seems to be missing from the brainscript documentation.

However, an extensive write-up is contained in the Release Notes for the 4.1.2 release. (The release notes can be found in the file "BRAIN Releases Notes.pdf" for 4.1.x installs and the "LAE (BRAIN) Releases Notes to 4.1.8.pdf" for 4.5.x installs.

I have filed a bug against the online documentation to include an entry for the unescape function.
