> Key: THRIFT-4461
> URL: https://issues.apache.org/jira/browse/THRIFT-4461
> Project: Thrift
> Issue Type: Bug
> Components: Delphi - Library
> Affects Versions: 0.11.0
> Environment: Delphi XE3
> Reporter: Anton Shchyrov
> Assignee: Jens Geyer
> Priority: Minor
> Labels: delphi
> Attachments: Thrift.Utils.diff
>
>
> In module Thrift.Utils daclared two methods
> {{class function CharUtils.IsHighSurrogate( const c : Char) : Boolean;}}
> {{begin}}
> {{ \{$IF CompilerVersion < 23.0}}}
> {{ result := Character.IsHighSurrogate( c);}}
> {{ \{$ELSE}}}
> {{ result := c.IsHighSurrogate();}}
> {{ \{$IFEND}}}
> {{end;}}
> {{class function CharUtils.IsLowSurrogate( const c : Char) : Boolean;}}
> {{begin}}
> {{ \{$IF CompilerVersion < 23.0}}}
> {{ result := Character.IsLowSurrogate( c);}}
> {{ \{$ELSE}}}
> {{ result := c.IsLowSurrogate;}}
> {{ \{$IFEND}}}
> {{end;}}
> But methods Char.IsHighSurrogate()/Char.IsLowSurrogate() **appeared in Delphi
> XE4. For Delphi XE4 variable CompilerVersion equal 25.
> In this way condition
> {{{$IF CompilerVersion < 23.0}}}
> may be changed to
> {{{$IF CompilerVersion < *25.0*}}}
> And access for unit *Character* may be determined through defiine symbol
> *OLD_UNIT_NAMES*
