specifying font-family in style css does not work

[nursmaul]

im specifying a font-family in the style css as below and have set its location in vscode preference>settings>extension as informed.
body {
font-family: 'Meiryo';
font-size: 32pt;
line-height: 29px;
}
Although the font-size and line-height seems taking effect to the output pdf,
but font-family never gets reflected. the font "Meiryo" is of Japanese font,
but the output font seems to be something like that of Chinese one. whats wrong.
