#310 Hebrew subtitles support

[Anonymous]

Hebrew subtitles are not supported.. while one can choose the Hebrew charset to have the characters appear as Hebrew chars, the text is inverted, because Hebrew is written from right-to-left. Also note that numbers and non-Hebrew chars are not RTL, so when coding this make sure the LTR-to-RTL code won't reverse numbers.
