Incorrect results with cyrillic symbols

Description

Incorrect results with cyrillic symbols.

Steps to Reproduce

When I try to use cyrillic symbols inside ScriptEvalStr function I receive unxpected result. I think that plugin passes incorrect data.

Script in QlikView:

T1:
LOAD * Inline [
Descr_,        Descr2_,              ID
адбцкон,     adbcend,               1
аебцнач,     aebcstr,                 4
абврф234,    abvrf234,              2
дбжх967,     dbjh967,                3
];

T2:
LOAD
	ID, 
	R.ScriptEvalStr('as.character(grepl("а.бц(кон|нач)", q$Descr_));', Descr_ )  as Grp,
	R.ScriptEvalStr('as.character(grepl("a.bc(end|str)", q$Descr2_));', Descr2_ )  as Grp2
Resident T1;

I got table:
ID | Descr_ | Grp | Descr2_ | Grp2
1 | адбцкон | FALSE | adbcend | TRUE
2 | абврф234 | FALSE | abvrf234 | FALSE
3 | дбжх967 | FALSE | dbjh967 | FALSE
4 | аебцнач | FALSE | aebcstr | TRUE

In cells ID =1, Descr_=адбцкон and ID =4, Descr_=аебцнач it should be TRUE as for latin set.
Plugin works with latin symbols as expected.

I checked R script in R-console and it works right:

as.character(grepl("а.бц(кон|нач)", "адбцкон"))
[1] "TRUE"
as.character(grepl("а.бц(кон|нач)", "аепцкон"))
[1] "FALSE"

Expected behavior

Right work with cyrillic symbols.

Actual behavior

Wrong result.
