Subject: [PATCH] fix(isAlphanumeric): include accented Greek letters for el-GR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The el-GR alpha class was extended to [Α-ώ] in #1238 to accept accented letters, but the sibling alphanumeric class still ends at ω ([Α-ω]). As a result isAlphanumeric rejects ό/ύ/ώ (and Ό/Ύ/Ώ) for el-GR while isAlpha accepts them. Match the range so the alphanumeric letter set equals the alpha set plus digits.
