Hyperlink in email body using SO10 text

Hi All,

I have created a standard text in SO10 which contains the email body text. In this text I have given &GV_URL&. In my program I have called READ_TEXT and TEXT_SYMBOL_REPLACE.
GV_URL Contains
<a href=https://something.aaa.jhjahd.sdf:9898/sap/bc/gui/sap/its/webgui/?sap-client=100~transaction=ZTEST">Click Here</a><BR>.

But ">Click Here</a><BR> is getting truncated in LT_LINES after TEXT_SYMBOL_REPLACE.

CALL FUNCTION 'SO_NEW_DOCUMENT_SEND_API1'
EXPORTING
document_data = lt_mailsubject
TABLES
object_content = lt_mailtxt
receivers = lt_mailrecipients.

I am not getting Click Here as hyperlink. Please let me know where I am missing.

Thanks,
HT
