---------------------------------------
What does your schema look like when it doesn't work?
> Issue when LIKE expression contains Chinese characters on Key column
> --------------------------------------------------------------------

> Key: PHOENIX-1334
> URL: https://issues.apache.org/jira/browse/PHOENIX-1334
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.1
> Environment: jdk 1.8 linux
> Reporter: wuyang
>
> When I use like expression in SELECT query. It works well when I put
> *Chinese* characters in LIKE expression on NONE PRIMARY KEY columns . BUT
> when I put them in LIKE expression on *PRIMARY KEY* , it occurs an Exception:
> select * from "test3" where PK like '中%';
> {quote}
> org.apache.phoenix.schema.IllegalDataException: CHAR types may only contain
> single byte characters (中)
> at org.apache.phoenix.schema.PDataType$2.toBytes(PDataType.java:216)
> at
> org.apache.phoenix.compile.WhereOptimizer$KeyExpressionVisitor.visitLeave(WhereOptimizer.java:829)

> org.apache.phoenix.expression.LikeExpression.accept(LikeExpression.java:269)

> ....
> {quote}
> the type of PRIMARY KEY and NONE PRIMARY KEY columns are all VARCHAR
> In the relative source code:
> {code}
> byte[] b = VARCHAR.toBytes(object);
> if (b.length != ((String) object).length()) {
> throw new IllegalDataException("CHAR types may only contain
> single byte characters (" + object + ")");
> }
> {code}
> actually, Chinese (or other non-Latin) characters will never meet the
> condition b.length == ((String) object).length() . Default encode method is
> UTF-8.
