Might be a stupid question, but...
As Catholics, is it ok to read and write using scripts that contain "indecent" characters?
Some of the ancient Egyptian hieroglyphs are indecent (and at least one or two are explicitly pornographic). (For example, some of the hieroglyphs in Gardiner's D class depict breasts and male genitalia. And supposedly there's an older glyph, not seen very often, which graphically depicts sexual intercourse.)
Also, some Chinese characters are indecent. (For example, the character for "woman"--and especially the character for "mother"--depict shirtless women with breasts. Though with Chinese, the characters are more abstract looking, so it's not as noticeable.) But I believe Catholic missionaries have historically used the Chinese writing system when dealing with the Chinese? And Chinese Catholics to this day use Chinese characters in their everyday lives?
(For me, Egyptian hieroglyphs is a hobby. And I can focus my attention only the other glyphs, but an indecent glyph might always show up in an Egyptian text as well as in the dictionary. You never know.)
