WoWInterface - String variables in C_LFGList.GetSearchResultInfo

Some addon doesn't work in my russian client. I tried to find problem and fix it. And found next problem with API and some string variables. API function C_LFGList.GetSearchResultInfo returns "name" and "comment" as string. But only print() LUA-command works fine with this string. There is an example of my code:

HelloWorld.toc

Code:

## Interface: 80300

## SavedVariables: name, comment

## Title: Hello World!

## Notes: My first AddOn

## Version: 1.0.0



HelloWorld.lua

HelloWorld.xml

HelloWorld.lua

Code:

local b = CreateFrame("Button", "MyButton", UIParent, "UIPanelButtonTemplate")

b:SetSize(80 ,22) -- width, height

b:SetText("Button!")

b:SetPoint("CENTER")

b:SetScript("OnClick", function()

        name = C_LFGList.GetSearchResultInfo(693).name

        comment = C_LFGList.GetSearchResultInfo(693).comment

        print("name: ", name,". String len: ", string.len(name))

        print("comment:", comment,". String len: ", string.len(comment))

end)

HelloWorld.xml

Code:

<Ui xmlns="http://www.blizzard.com/wow/ui/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.blizzard.com/wow/ui/..\FrameXML\UI.xsd">

        <Script File="HelloWorld.lua"/>

        <Frame name="HelloWorldFrame">

                <Scripts>

                        <OnLoad>

                        </OnLoad>

                </Scripts>

        </Frame>

 </Ui>

Result in game:

Code:

name: the shard of heaven farm wm of. String len: 8

comment: осколки небес фарм вм оф. String len:8

and saved this variables in file "...World of Warcraft\_retail_\WTF\Account\...\SavedVariables\HelloWorld.lua"

Code:

name = "|Kr730|k"

comment = "|Kr731|k"

Possible problem with UTF8 charset, but UTF8 addon also doesn't work with these strings.

Update: the same problem is with EN game client.
